Does anyone know if Cadillac Deville seats from 85-93 can be installed in a G-body?

Any seat can be installed in any car with enough fabrication! Chances are that it won't be a direct bolt in. The easiest way would be to use the G body tracks and adapt them to the Cadillac seat.

Most GM seats interchange well. I have never tried Cadillac seats but I don't see why they would be much different.

Check the width of the seats in the Cadillac. I wanted to swap seats from an early '90s Pontiac Bonneville SSEi into my Monte Carlo, and because of the width of the Bonneville seats, there wasn't enough room between the console and the door, for the Bonneville seats to fit. If you have a split bench seat car, something like that might possibly work.

Would anything be different with mounting them to the full bench seat bracket bolt pattern(not the 60/40 seat) on my car?

The Deville seats are buckets. They have two tracks per seat. Your bench only has the outboard tracks. You are missing the brackets welded to the floorwell that the inboard tracks bolt onto. So yeah, this is not much different than the situation that you would encounter with any buckets, including the "correct" G-body buckets. However, the spacing between inboard and outboard tracks can be different, for example, in 3rd Gen F-bodies the spacing is narrower. You can get the brackets to weld in, but they are shaped to fit the floorwell shape exactly where G-body track spacing expects them. If the track spacing is different, or you just don't want to weld the brackets in, some kind of adaptation will be required.
