It's a pain in the ass, but the solution seems to be just breaking the FX up into transactions of >10K USD, of slightly varying sizes. Their AML flagging rules are very stupid and don't seem to flip out about that pattern. In my experience anyhow.

have you considered opening a local account there next time you're there for a visit? Then you can xfer to yourself which is one way around some cross-border nope-nope-nope regimes. Wise at least seems to be satisfied with that (admittedly after significant ID checking).
