I'm guessing the panels are some sort of FRP? Not a pressboard panel with a coating on the surface? You should use the right adhesive as recommended by the manufacturer. Some types of Liqud Nail can "burn" though and leave discolored lines on the panel.

The adhesive should adhere to the backer no problem. Just follow the instructions on letting the adhesive set-up correctly.

I'll leave any questions about waterbarriers and such to the pros.

Why are you using cement board if you have panels? Did the manufacturer instructions say so?

The backerboard won't suck up the adhesive, but the board tends to suck moisture. I would just dampen the board down with a wet sponge first to be safe.

mud...the FRP panels are completely waterproof. The only weak spot is the joints as you know. Eventually caulk will fail and let leaks get through, even if you don't see it. The backerboard and a moisture barrier will keep it from getting to the framing. Cement backerboard is not waterproof, just it won't fall apart and mold/rot like sheetrock.

No reason NOT to use it, just more expensive.

Lots of people where I used to live, would use sheet plastic, sheetrock and FRP..but you couldn't expect them to last w/o mold forming.

No expert..but yeah, the inside corner beads designed for the panels and caulk..thats about all you can do. The beads are less than $2 for each 8' piece.
