Let me ask you a completely different question... what do you want to achieve by splitting the sheets? You are faced with the same problem as if you split the sheet into two parts: keeping them safe so that no third party can access them.
Splitting the sheets even more only bears the risk of making a mistake during the transformation or recovery. In my opinion, the added value of frequent splitting is - compared to the effort and the error-proneness - quite low.
If you are doing this for another reason (trying out different methods of how to split the sheets, ...) then this is of course a different issue, but I don't think so because of your question.
I want to be able to construct the orginal back from only two parts, so if i am able to lose one or even to parts, i can construct it back anyway. I also want the extra security that if someone only find one they cant use it. If the hiding spot i was thinking of was a lot worse than i thougt and some people find it, i dont want them to be able to get any information from that and get acess to my fund. I know I need to construct them back one time, but i can do that mannualy, so the only thing I need to trust with my hole private key is ledger. But I think that is safe enough for me
