You can't send the result of
selfdestruct to multiple parties.
What you could do is
self-destruct to the address of another contract, and put the splitting logic in that contract.
However, unlike a normal payment to a contract,
selfdestruct doesn't automatically invoke the fallback function, so you can't do any splitting in that call. You'd have to simply let the value accumulate in the receiver contract, then have the recipients make another call to the receiver contract to send the funds found in its balance on to wherever they're supposed to be split to. You may prefer to have each of the recipients each make their own call to withdraw funds, as this avoids problems with failed sends affecting other users.
