Those are 2 big "ifs". The incentives are completely misaligned and the platforms work for the companies. They would now have an even bigger incentive to stonewall and close valid issues than they did before.
They already like blurring the lines by rejecting reports that have clear reproduction scripts, videos, demonstrable (but not critical) impact. They'll close it as "not a bug" but then also forbid disclosure and stonewall mediation requests. Reports are supposed to be kept private until the issue is fixed but the system gets abused to cover up issues long after they've been fixed.
In some cases I strongly suspect it's to evade liability for financial damages that their customers might've suffered. Platform mediation always takes their side and if you want to do what's right, you will get banned.
It's not a horrible idea... the challenge there would be making that payment/refund flow totally transparent in order to build trust and be fair to the researchers.
Making, payment/refund setup is more complicated than „set and forget”.
First question: Do you keep money for shit reports?
Well no, you have to pay it back like credit card validation. There is no pain for posting shit report just inconvenience. There is no legal way where you can keep the money.
