[FT] B5 miniatures

I'm rather happy about the Fleet Scale minis I received, but looking
at AOG's page brings up a question.

How well do the current miniatures scale for FT?  The up and coming
B5 miniature looks slightly larger than an FSE SDN, which is what
I would want for a full size space station.  Now, what I'm using
for scale is the hex base.  Does anyone know if they are using
the standard size hex bases?
