You should try to avoid doing things that are not "standard" because if you are lucky the worst thing that could happen is that you will have a lot of problems recovering your funds by duplicating that self-defined process but if you are not you would be creating a weaker method that could endanger your funds.
Try to stick to the standard defined methods that are created by experts and are used by many implementations and their users.
It's like saying "how difficult is it to get to Pluto vs how difficult is it to get to Jupiter"... For all intents and purposes, they are both "impossible".
I love how my analogy is catching on
