Now, It would be perfectly fliable as a model, but you have to be ready for possibles snaps at high speed ( if you turn the other way), fast landings, and so on....
Should make a very "interesting" model, if not very relaxing.....

First I have heard of that. Do you have the names of the planes with an assymetric wing trim? Rare Bear has the same wing clip outboard of the wing fold and it's the fastest prop plane on the planet. Pretty sure Strega and Dago Red are also symmetrically cut.
Just curious,

To the original question, I trimmed one bay off the old TF P-51 (red box) back in the early 80's. I turned it into Dago Red. It didn't seem to fly any different than the stock P-51B that I had at the time. Just keep the airframe as light as you can if you are going for a major wing cut.
Good Luck
