Even more direct: use coinbase outputs of=C2=A0 XT blocks to create those o= utputs, as they can't by definition be on the Bitcoin chain.

If you can't get those, using coinbase outputs of Bitcoin blocks to cre= ate "definitely Bitcoin-only" outputs, and then spend the inputs = to those transactions again on the XT chain. This isn't quite as good, = as a big reorg on the XT chain could in theory spend them, but it's a c= lose second.
