With any luck, it should be little effort required as it looks like you have the block device support in place? This filesystem actually should in theory work fairly well with brd, because then we wouldn't have to bring the data over into pagecache for frequently used pages but we can retain the compressed storage for the infrequently used stuff. I say in theory because I don't know of any serious users (except kernel testing) of brd :)
