Yes, one could add a nonsence CAS to existing incref/decref, and measure overhead.
That would be the first thing to do IMO. If it doesn't seem to decrease performance a lot, you could continue by adding locking to dict objects, and measure again. Then add lists and sets (although I doubt sets and even lists are performance-critical for general interpreter operation). If after that you have less than a 10% slowdown (personal opinion only, other people's mileage may vary), it's probably worth going on and trying to do the whole GIL removal (which doesn't mean it would necessarily be accepted, by the way, but at least would avoid it being automatically rejected ;-)).
