@Beast your K311 looks great - I don’t think I’d be brave enough to try the camo, though I might try the body work. I also bought one of these kits, which as you say above, goes together well. Your real-life M715 is a beauty! 
I concluded that this truck was also close enough to a Jeep J10 Honcho that I could convert it. And, as you also note, it is in some ways similar to other Jeep/Kaiser vehicles, but it’s not exactly close to them. Nonetheless, I gave it a try:
I could rationalize the basic proportions of the K311, but to your point, well - beyond that, it needed a fair amount of work. For the J10, I had to make several concessions, and opted to try and address three key elements: the cab, grill, and hood.
This turned into a lot of work, with pretty good, but not necessarily accurate results. It’s funny (looking back now, not at the time 
) the differences were subtle, yet a real challenge to fix - the front of the front fenders on the J10 are more angular and tilt forward (next to the grill); the grill is different; the hood is raised in the center; and the cab completely different.
I wonder if there is enough plastic/room for a cut on the front fenders to allow for the circular wheel openings on the M715? An obvious first step would be to shave off the front fender flares, then see if you could carve out the radius/close to the wheel opening on the Jeep. Then, try and get the hood to look more similar. In the J10 build, I added the ‘hump’ to the hood using evergreen, but, if I did this again, might try and slice along the edges of the ‘hump’ from the front of the hood toward, but not all the way to the back, bend it up, and fill the gap so it looks more like the M715?
Anyway, your K311 looks the part -
Cheers
