I don't know the exact process but I don't see why they couldn't do that. Parliamentary supremacy means that Parliament is supreme. What they say, goes. It's a dictatorship of elected MPs, hopefully kept in check by the need to be elected.
They can't do that because it would make a mockery of the legal system. Parliament does outrank the Supreme Court, but they do that by passing legislation, not just having a vote and going "no, sorry, lol". The whole legal system is built on precedent, which is incompatible with parliament overriding it piecemeal.
