On the one hand it would be nice. On the other hand internet is full of quite amazing Montesa conversions....
I mean, the santiagos are great sculpts. Its just they also happen to be old style metals which makes a lot of their bits very fiddly.
BS and Combi Santiagos are also what I'll use to make my own Magisters, since I really dislike their new sculpts. The running Santiago remains one of my favorite models in the game.
I wonder if Magisters will lose Panzerfausts on all their profiles due to models not having them.....
