It is possible to replace client.wyc from "execute file" after "updating is complete"

It is possible to replace client.wyc from "execute file" after "updating is complete"My requirement is such that first i want the patch to apply

for e.g. R4 to R5. But after applying i want the client.wyc change to R1.

In my opinion, sure you can do that, but you lost all information in case you must uninstall the update previously applied.

The Client.wyc its a file in your application directory, so you can modify it, but it's used by WyUpdate, so if you modify that file, do not expect WyUpdate acts correctly.
