I’d advise discussing these splitting ideas w the folks from podcasting 2.0. I’m sure they have some ideas. But they also have explicit minimums on the split. Can’t split less than 10 sats for example. And the fee distribution is very visible for the users.
Single splits seem fine without too much overhead / fee costs. 10 splits at best cost 10 sats. At worst could be much much more, rendering it infeasible. Maybe down the line when LN is much larger we can have better fee estimation but atm it can vary WILDLY.
