I do not believe that Progress or ISS flight rules would allow a Progress to hang off a docking port in soft dock mode for more than a few minutes, so an EVA or RMS ops are unlikely. Also, the multiple undeployed pyro bolts make this risky for EVA.
Apparently there are no flight rules forbidding that. It has been done in the past, here is example: http://en.wikipedia.org/wiki/Progress_M1-7 The Progress was hanging on the probe for several days.
IF the Kurs antenna is obscuring the docking collar and preventing the hooks and latches to engage, I don't think the flight rules are going to allow the Progress to sit there in soft dock mode for very long.
It's close...
picture of m-11m below, assuming its the kurs antenna on the right of the picture, if its the other one, its blocking the docking collar.

And a picture of m-14m showing both of them.

NASA:
Managers meet tonight to determine if Progress will press for docking. If approved, NASA TV coverage begins Fri@6:30a- Docking planned@8:26a
I like that "If approved" surprised this wasn't questioned at the congress meeting yesterday.

It looks bad, but don't forget that there is a separate pyrobolt that can be blown to move the antenna away, just before docking. The question is whether that additional pryobolt system is also dead.

Seem to remember explosive bolts that needed to be replaced somewhere on the ISS like last year. Anyone remember that?
The issue was pyro bolts on the Soyuz, based on a previous failure
Pyro bolts connecting the PAO to the descent module. Different system.

Per the evening DPC. Standard docking planned and belief is that a good seal can be achieved with the undeployed antenna.

Russian crew is being asked to photograph the Progress antenna with the best lens possible. The cupola shutters are usually closed during dockings (thruster firings) so photography from there probably isn't an option.

US crew has told Houston they are willing to help with photographing the Progress as it approaches. CAPCOM reported that video from both the Progress and of the Progress from the ISS is planned for downlink to document the antenna configuration.

Is docking(-attempt) still at 8:26 a.m (EDT) / 1226 UTC?

Appears so until otherwise noted...

I wouldn't expect anything else from "managers". It should be engineers who make a call, not managers.

no this is managers from all MCCs to ISS-MCB who decide and agree with risks. Information is from the engineers and this info is passed up MCC chain of command and given to ISS-MCB Manager chain of command and they determine plan. Majority of these managers were engineers when they started.

I got the tail end, so not 100% sure, but thought I heard no go for docking...
Which is in line with the analyses just posted on L2.....

Good Morning, Earth! The Progress resupply ship approaching Station has a failed, obstructing antenna. Roman & Pavel will manually dock it.
