The shuttle couldn't carry anywhere near enough fuel to change their orbit that much.
There was a proposal to put an ion engine with a big fuel tank on Hubble to slowly change it's orbit to match the ISS, but it would have taken years and just wasn't worth it. Hubble is full of 20 year old components and it's a minor miracle it's done so well for so long.
In the end, it would be better to just build a new scope and put it in an ISS compatible orbit if you want to make it servicable.
Shuttle launches don't actually cost that much, but keeping the program alive longer to accomodate those launches does.

I think this post would have benefited from some punctuation. So let's break it into bite-size chunks, and tackle them one at a time!
I know they wouldn't do this because it would be to expensive but would it be possible for them to launch Atlantis to Hubble and then Launch Endevour to Hubble at the same time with plenty of extra fuel
Yes, they could both be launched - this is the backup plan should Atlantis become disabled on-orbit - see STS-400 related items. But there is no place for all this extra fuel you are talking about. I don't even think a payload bay full of fuel (which can't be done) would have enough delta-V to make the plane change required from Hubble to ISS.
and then while carrying Hubble Atlantis get within grappling rang of the SRMS so the SRMS could grapple the Hubble then the shuttle would release the Hubble then dock to the ISS
Again, the planes are too far apart to make this feasible.
and then the shuttle could return home and the next logistics flight could bring any other Hubble equipment that was not able to go in the first flight as a side item to the already scheduled MPLM then after the components were installed after the mission by the ISS crew the SRMS would release it into orbit some how? I know this would never in a million years happen but could it be done? Just to think outside the box. 
I can't for the life of me understand this part.
This thread should be merged with Shuttle Q&A.
Thanks
You're Welcome!

The orbiter doesn't carry enough propellant to the plane change

I was doing some reading the other day about Enterpirse (OV-101) and the ALT at Edwards.
Did Enterprise have Fuel Cells installed or were they using batteries of some sort? Obviously weight was not an issue with no MPS or other flight hardware installed.
And along the same lines What about the APU's?? Were they Hydrazine fueled units like the space rated fleet or were they doing something else for hydraulics??
Are there any interior pictures of Enterprise as she sits at the NASM? Flight Deck, Cargo bay.. The outside looks good but it would really be interesting to see what shape she's in on the inside.

The same as the other orbiters

Not to jinx the program, but what's the procedure for a hung ET SEP? If the pyro's don't fire? AOA? EVA? other? thanks.

The only hope is to drag the ET into orbit and hope to sep later or get a rescues mission.

We've been discussing it on spacevidcast.com, wondering if there was time to open the doors, use the arm, EVA (even without pre-breathe...eesh), ditch the payload, and/or try to pedal up to the ISS after a circularizing burn. One suggestion of even possibly using the atmosphere to pull the ET off the mounts on reentry, but the body flap or other black stuff being in the way is a bit unsettling.

Pulling is away from the belly, entry would push the ET into the attachments

aye, another suggestion was flipping over, with black side up. needless to say a likely catastrophic failure.

The cheapest way to get Hubble to ISS would be send up a Shuttle to retrieve it to the ground, then put it in another Shuttle and send it back up! 8-)

Ya but Hubble no longer can fit into the payload bay. Next question: What will they do about not having a RPM for this mission as the Hubble is not the ISS?

It still can.

Modified OBSS inspections.

They're going to shoot the RPM with Hubble while the Shuttle is still a quarter of an orbit away.

That's correct. Some appendages might have to be jettisoned if they can't be retracted fully.

Modified OBSS inspections.
Also correct. RPM is not a requirement even for ISS flights but it does greatly reduce the time required for OBSS inspections.

So I was at the Air and Space museum (the one by Dulles) today and noticed a few things.
First that the original test panels were replaced on the left wing of Enterprise. I thought they were going to be left off as a symbolic gesture to the trials and tribulation after Columbia. They still have the scars and marks from testing though.
Then I noticed there is a section of authentic tiles with some simulated or legit impact damage on the LH landing gear door. Whats the story with that? no one could explain it to me. When I asked what that was about, the guard there mentioned "ohh those arent real tiles, this shuttle never went into space", but that section had real serial numbered ceramic tiles that were visibly different than the simulated tile structure on the OV-101.
The museum rocked, I am so happy I finally saw it!
