The conversion kits contain everything you need to run over 30 ships but it's going to be rare that people's collections line up with exactly half the number of every ship that can fit into a list rounded up.
It probably means some ships with models but no gameplay components and it almost certainly means a lot of gameplay components with no models.
Ships without models. Models without ships.
Hm.
Which ships do you think make the best stand-ins for other ships? For me the TIE/v1 is pretty much just an upgraded TIE fighter anyway so that can get a TIE/ln model. The TIE aggressor is pretty much just a TIE/x1 with its wings clipped so that can be a TIE/x1 variant. Small base rebel shuttles? Let's just say there are a lot of different HWK models on the market now. Shadowcaster and Jumpmaster? Scum YTs.
