Thanks to Jaina and Finback on these boards I managed to pick up the materials to make a classics Brawl.
Base body is the two-pack deluxe Megatron. I used the arms from the deluxe Optimus that was in the pack as well, and the left shoulder joint from a second deluxe Megatron I had. I had to do this because the right shoulder joint has a different arrangement to accommodate the original's spinning arm.

Here he is with the cannons from a KO G1 Brawl.

One downside is the cannon barrel isn't firmly attached in tank mode. It's held in place by the arms that form the turret.

I rearranged his feet so they fold away properly for tank mode, but then put his legs on backwards to emulate the G1 Brawn and to differentiate him from Megatron. This also required cutting down the original kneepads.

I cut up a toothpaste tube for his mouthplate. Ideally I would have liked to have used a Grimlock head but I don't have any spares. Also I suspect the head on this mold is attached via a metal pin, so putting a new one on would have been hard.

I drilled a hole in his back and in the gun barrel connection, then put a plug in the hole in the tank that the gun can hook on to for robot mode. Luckily it doesn't get in the way of tank mode.
As for the other Combaticons, I have universe Onslaught and a custom Swindle. I'm pretty clear about what to do with Vortex, but getting Blast Off to work is taking some doing.
At this moment they are non-combining :(
