This was an interesting thought experiment for me, but upon reflection
there's no point in trying to do this in Lightning.

Everyone considering a pledge can sign their part of the transaction,
for free, if they hold any coins on the Bitcoin blockchain. Only the
initiator needs to pay any transaction fee.
