The Martin B-26 configuration can be adapted quite nicely to CL Stunt proportions. Tom McClain did a serious model of it basically with full scale dimensions/proportions.
One reason it would work well is that it is fairly short coupled with a horizontal tail with a good amount of area compared to many full size aircraft with comparatively long tails and small horizontal tail surfaces. Fuselage and engine nacelle diameters can be dealt with for a semi scale stunt ship a bit easier than many radial engine twins.
