Not something we've ever considered. I did a bit of thinking and I've come up with a better solution though.

I've made a new account called 'RubbishBinDump'. I've also given this account 10 million qi. In this way you'll be able to send item to it that would otherwise be untradeable because of the high qi limitations. I've also changed the seishin joke item to be an actual item in the misc category as opposed to being in the subscription category so you can send it to the dump account too if you wish. If any items have a qi cap higher than 10 million let me know and I'll adjust the numbers so that this will work.

Be warned though: this account will not be monitored or checked and any items sent there will not be retrieved for you if you make a mistake. Send at own risk - only send items you are never wanting to get back ever again.
