Reply to Arcade after applying SE overlay?

Hey guys, I was wondering if it would be possible to apply the arcade mod to my vci after I have already applied the standard SE overlay. Would I have to buy another overlay, or would I be able to do some fancy razor knife work? I have yet to buy either overylay, as I'm still waiting on my vci to come in the mail.

Actually, can you even dissemble the case with the overlay applied?
