Currently we do see an issue with many transactions clogging the queue. Could we convert the wallets to broadcast anyone can pay transactions so that any wallet that sees the transactions could append to it? That would mean many people could accomplish all of their moving in single lump transactions. Perhaps just by letting anyone can pay transactions be rebroadcast and used if available is a better solution. Could that also be a great method of mitigating dust attacks on top of keeping the minimum send amount?
