multi signature – Spending paths for subset of n-of-n multisig

I wish to obtain the next.

A gaggle of N individuals come collectively and create an n-of-n multisig. Every of them funds this multisig with a customized quantity of bitcoin. In some unspecified time in the future sooner or later, they resolve to spend these funds, nonetheless a subset Okay of the preliminary group has disappeared or just isn’t reacting anymore.

Is it potential to attain the next habits:

• The Okay people who find themselves not reacting are getting their initially contributed funds again
• The remaining (N – Okay) individuals, who can be found to signal, agree collectively the place the remaining funds are despatched to. Principally as if the multisig had been an (N-Okay)-of-(N-Okay) to start with.

I believed one potential approach (please right me if I’m unsuitable) could be to make use of some taproot performance and embrace varied spending paths within the merkle tree that permit all potential subsets of customers to spend as described above. This might be achieved by presigning a bunch of transactions upon the creation of the multisig that use these totally different spending paths. These transactions are signed in a approach that outputs returned to the non-reactive customers are outlined forward of time and for the remainder of the funds, the remaining customers have to resolve and agree unanimously the place they need to ship them to when the time for it has come.

Would this work? Even when the reply is sure, with a rising variety of customers N, the combos of subsets explodes which makes this infeasible, so perhaps there’s a higher approach.

Thanks very a lot on your suggestions!
