If you are so interested in these kinds of things, you should study the problem first. You seem to overlook some basics of Bitcoin. The current stakeholders, i.e. ASIC owners, have no interest in giving up their money printing press. To make changes to Bitcoin you need the consensus of those who have mining power and developers ("community consensus"). That community consensus is very clear. Bitcoin will never move to PoS.
I am afraid you are mistaken. If the coin creation method is changed, the ASIC owners have nothing to say. Only the economic decision of the coin owners will matter. If after the fork everyone tries to dump the PoS coins, it proves they are worthless. If everyone tries to move to PoS selling their PoW coins, the previous version with ASICs is worthless.
