@bbobrob there may be some merit to that! Neo Genesis did have a second print run at some point to introduce corrections to various cards (see here and here). I have some of the rarer correction cards but I don’t have the original errors to compare them against, I’d be curious if anyone with the error and corrected versions could check the cardstock of these side-by-side.
I’m hoping they’re the same though - whilst it would be a nice niche variant I don’t especially want to have to try to track down a different cardstock Pichu!
