Just send it to wallet to new wallet to new wallet a few times. Easy peazy and cheap even for people with only pennies.
Stop playing games and use it “by default” like how it’s intended and it even defeats the problems most apparent in “breaking monero” series.
How did you not figure this out already?
Hm I believe it depends on if you combine outputs from both wallets by doing so but you’d have to talk to a decoy expert about that.
