I would suggest the following option
SoD - Diamond, m200, Mini-nosta, +1/+2 (so that SoD has equality in templates)
VT for SoD - SM-ka, Jeb, mm6
Mirror - Full
I think the version can always be agreed upon on the spot.
The SoD players will have equality/advantage in templates, and the VT player will have a choice of which template to play for SoD.
The training base in pictures and in reality are 2 different things; this could be confirmed in a positive way during Odessa, although it looks quite interesting.
