LEV/Class 141 cabs

[JDW]

Hi, I was looking at the latest ModelRail, and an idea that I've had in the back of my mind for a while came back to me, first inspired by posts by LongRail on his thread a few years back:

From wondering about LEV1, I started to think about creating a class 141 from the same bus bodyshells, but of course the cab end is different, which led me to think of 3D printing.  Now, I have no idea about such things, so my question is whether there's anyone out there who has already done such a thing, or might like to have a go?  My thoughts being that a cab end with cabside window and drivers door could be mated with cut-and-shut Leyland National shells for a 141, but could also be used to create the later LEV version(s) with 141-style cab, without the external cab door.  Anyone with too much spare time up for the challenge...?
