Listen, wait for the author of the uncensor patch to work his magic with a v1.22 if he can/wants/has the time & effort, otherwise what 'TheBlueKnight' said boils down to getting a v1.21, getting a v1.22, decrypting both (and the uncensor patch, for it also is packed into .wolf files afaik), comparing them and thus learning which (asset) files were changed between the two versions and only overwriting with the decensor patch's decrypted files the ones which haven't been changed during the version-up. Otherwise the uncensor patch may (well, probably) eff your v1.22. And I have no idea how "partially" that would make a v1.22 uncensored, at any rate.
You don't need to repack it. If your .wolf files are correctly decrypted and you rename/move those .wolf files, the game will access the assets directly, from the decrypted directories. (but it always looks for .wolf files first, which is why you have to move/rename them)
