I apologize if this is severe necro-ing or something like that (actually took a break from Payday for a while), but I did want to check and see if there was still any interest for this project. I think a "boxy" MGS style LAM for the Interceptor would still be really cool (and pair it with the Champion's suppressor and you're set), but I also know it falls within the realm of modelling, and is a lot more involved than just porting a model over from another game.
