Ben- It is like most things ... if there is a will there is a way. That said, I think you could perform the necessary steps if you are really careful and have lots patience. However, my vote is make it easier on yourself, bite the bullet and remove the skin covering the avionics bay.
There is a connector that needs to have pins removed/inserted which may be tougher to access and you will be able to do a much better job of dealing with the metal chips if you need to cut the panel yourself.
Also, if memory serves me correctly, the wires for the AP module also go to the AV-50000A interconnect module so you will likely need to remove the SkyView for access so that connector can be installed.
