Simulate given Stability Derivatives onto a Generic Plane?

I am trying to test out multiple theoretical airframes and stability derivatives on an RC plane without having to actually build multiple different planes. Is there a way to use QGC/PX4 to simulate what flight would feel like with a theoretical airframe, while actually flying one generic airframe? I would like to actually fly it, not in a sim. I have AVL files of our plane, I could also make an sdf file. I essentially want one airframe to “behave” like multiple different ones for testing.
