Couldn't you just send a wire?
It's worth bearing in mind that most financially motivated criminals are after easy marks. If you're too hard or expensive to hit, they'll find another target. If you're seeing like a bank, that's a victory and the protocols are doing their job by reducing fraud.
$20-ish to move 200k safely is nothing. If you are doing it internationally, it's typically tiny compared to the FX cost.
Point is, wires are cheap for what they do. They aren't your only option, but all options have tradeoffs.
As I said, there is a range of cost/risk/PITA options available. This is niche enough I don't think it's particularly worrying the banks don't support it easier.
