Not really, not in a way that would solve this sort of problem.
Who would pay that cash? Where would the money come from? How does the buyer valuate that money coming out of somewhere when figuring out their offer? How does it interact with the preferences on the investors’ stock?
I guess similar to how stocks work, but instead of having to wait for an IPO, the acquisition price would be distributed proportionally to all of these "acqui-stock" holders.
