If you are able to get the shadow 2 frame registered to you, that is basically all that matters.
Legally there's nothing you'd have to do if you temporarily swap the 9mm slide on.
If I recall correctly, if it's a "permanent" change, or you have it on for more than a month straight, then you technically have to report the change in caliber. I don't know if the CFO would be happy about updating your registration cert to say 9mm.
All that means though is just don't create and share a chain of evidence that proves that you've "permanently" swapped the caliber.

Any other 22LR pistol recommendations?
Something that has a 9mm slide that swaps right on.
