Technically it was done a while ago, but now there's a comm for it! The hull gun on the front is magnetized and can be swapped out for a laser, and the sides are magnetized as well so I can put sponsons on if I ever get around to having some 3d printed. The turret-hull connection is just a giant circular hole so it pops off real easy and I have taken to blu-tacking it in place for transport/games.
The actual name for the model is "Mars Alpha Leman Russ Incinerator", and I run it as an Executioner in 40k.
Behold, the warm glowing warming glow of the turret gun (which I'm still not really happy with even after like 10 revisions):

Nice paint job. Just noticed this comm. Sorry for the late answer. Im about to get back into 40k with the 10th edition so I might post some pics here end of this or early next year.
Thanks, and no worries for the late comment! Always good to hear praise, lol. And yeah, I won't be able to post anything new for a while either, because I paint so slowly. This tank was like a year from primed to finished with other stuff in between! That said, I have around 1k points of stuff finished that I might slowly upload.
Oh, and I think /c/hobby might be more for this kind of thing but I just cross-posted to both.
