Per the NPO Lavochkin website dated 30 May 2018 of new version of Fregat-SB called Fregat-SBU planned for Soyuz-5, Angara-A3 and potentially Angara-A5. A formal tender for Fregat-SBU series development is in work. Fregat-SBU is a planned universal replacement of all previous and current Fregat versions.

How would that work given the different mass capacity/performance requirements of each? Something like Fregat-SB or Briz-KM with a main body and then a drop tank, and then either resize the drop tank or add more depending on the LV?

It is not possible to answer that at this time. Unlike current launchers Fregat-SBU is purportedly sized for missions using 4 and 5 metre payload fairings. The design apparently takes the existing design features of Fregat-MT and Fregat-SB and combines them with new yet to be revealed features/technologies. I have asked certain people for a graphic of what it is expected to look like. Hopefully more info in the coming months.
