Do you use SteemPeak? There's an option to use a third party service to be able to receive 100% of post rewards as liquid so if you wanted to send the entire post rewards rather than just the liquid half you could. I haven't tried it out because I've never had a reason to (if TeamAus was doing more fundraising that's about when I would have tried it out), just noticed it as a payout option that needed to be enabled on the services page.
It does of course require trusting that third party XD
