Have you ever done anything like that before? Using a chisel to chisel out your hinge points is pretty tough and if you hasn’t done it before odds are you’re going to either go too deep or chip the frame away

If it’s just an average interior hollow core door personally I’d probably just buy a new pre hung. I’ve got a lot of experience with this type of thing and I’d be pretty hesitant to do it. If I was going to I’d definitely be looking into buying a jig or renting some sort machine which cuts those grooves out for the hinges as opposed to trying to cut it myself
