Don't really know exactly. I have barn doors on the 'Hoe, so I can't use mine for reference. But exterior-wise, you're going to be looking at a filler panel, and the same treatment as filling any handle. Innard-wise, I believe if you're not worried about not being able to open from the outside, you could get away with simply using a PU relocator. Otherwise, you're going to have to get into some form of electrical popper/lowering mechanism for your lock/open.
