So I have to ask, what is the point of this thread? It's an entertaining scenario to ponder for a minute, but the reality is that it will never happen for too many reasons that I care to list here.
If a vast percentage of regional-airline pilots were to quit, I reckon that it would quickly force airline management at least to take into account what is being demanded from them. There is just no way that the airlines could replace those pilots in time as things stand currently with retirements and what not, but...
...good luck persuading folks to cut off their means of supporting themselves and their families. Some pilots will even take advantage of the situation as noted by others, and use the opportunity to upgrade and to reap the rewards of those who would quit or strike. I can't really blame them, either. The whole gist of the OP sounds so laughable that many would just laugh it off immediately.
