Regarding those designs and heat dissipation: Have you considered a finned design like on this Lazer I once have seen in an ebay auction?  
One could also raise the rear top deck connection base and bolt the top deck bottom up like this:
This would increase the connected area between the fins and the top deck mount and "increase the space" below the top deck for bigger non saddle-pack lipos, since you could push them a little bit farther to the rear end.
Of course it would be annoying to assemble into the car and you'd have to consider different upper deck thicknesses. Last but not least Welshy's belt tensioner design would have to be changed, but hey, it would be more blue aluminium 
Another question: Did anyone ever considered 3d printing to create some spare parts? There are quite some shops which offer Nylon 12 as material, which might be good enough, at least for some front bumpers or maybe some C-hubs.
so long

That is a kewl concept.
But as Welshy stated before, the finned heatsink motor plate is enough.
I see 2 concerns there:
1. Those fins can only be most effective if the base is attached to the motor. But since the motor placement moves if you switch pinions, it may be tough to attach them to the motor and still have no interference.
2. With a fin that big on top of the rear upper deck, the center of gravity may shift upward. Although it's made with aluminum, it will still affect the cog. I would choose a hot motor over more body roll.
That's my 2 cents, but I still have to agree it's a kewl design.
