Chaining not-yet-signed transactions is impossible because transaction inputs are identified by the previous transaction's hash, and the transaction's hash includes everything about the transaction, including the signatures. @p{par}

A multisignature transaction taking funds from #1 and paying them to #4 that requires signatures from #1, #2, and #3 should accomplish the same thing, though. @p{brk}
