Hi Nick, afraid not, no problems at all..
I actually took the L1 a bit too far on its frame width.. In theory it shouldn't work as the wheels rub on the frames, and so should be shorting, but I think with probably more luck than I'd like to admit it's okay...
I like the idea you've had, but I'd be a little worried that it might not look quite right.. I'd be tempted to have a little mockup.. Or just build it in S7... Awaiting the flames...
