Yes, it looks awsome. But as for working, I dont think so. It can work if the crank case is divided such that only one cylinder uses a spcific crank volume and the other cylinder uses another part. Also, the once carb and one induction crank port is not wise since the induction timing would not be in proper sinc as you can get on a single cylinder loop scavenging nitro engine.

For this engine, I would have staggared the the cylinders so that one is slightly further back than the other. With the cylinders staggared, I would give each cylinder its own crank case volume. I would have used 2 independent carbs with a linkage to actuate them in sequence. I would put the second carb on the rear of the engine and thus, its own crank induction port on the rear of the engine too. Though it is possible to use a single crankcase volume for two cylinders, it is not that possible on a V configuration. I would have used an opposing boxer style configuration.

Also, I think it would be best to use one tuned pipe for each cylinder. But it is possoible to make a single pipe for both cylinders, it will be trickier to design the expansion chamber to make the return pulses reach each exhaust port at the right time. Of course, you would have to know at what degrees each cylinder reaches TDC.
