My thoughts are a resounding YES. I have considered the idea of a V tail elevons variant. That is what you mean, right? 3ch, V tails do it all?
Go for it. it will be different and a tradeoff in some areas, but will be a great plane. This is how I see it handling; rolls will be less axial than a regular Arrowhead and turns a tiny bit more "ruddery" feeling than regular elevon or aileron turns, though not completely like a RET plane. Stability should be roughly the same, and high alpha maneuvering and control should be noticeably better with the V tail setup.
