This is surely a great idea when you have filesystem-level snapshots (as you have in btrfs). This sounds like something that can be easily written as a proof-of-concept implementation in a shell script. Once you work out the exact mechanics, we can consider either adding this to pacman or as an external wrapper to pacman, whatever makes sense. (This would be a discussion for the pacman-dev mailing list.) What I'm saying is: If you have a more detailed description of how this scheme should work, preferably together with a simple implementation, then a much more fruitful discussion will emerge.
