Actually I'd rather see the novel TK5...
Didn't Breezegone post models of some of the neo-Tholian ships, which included different command modules? If i were doing this myself I'd be retexturing the aft hull and replaing the boom with these modules. Then again, with no Tholians ingame...
Here's a good pic of the TK5...

You could also try meshing a T-PC with the current ingame KA F5 to see how that works out.
