I'm now a firm believer in the benefits of a DSB. The tank really will become self sufficient after about a year, and the anemones will love you for it. I'd combine the sand.

Moving those anemones to the 55 shouldn't be a problem. Moving the sponge could be since you would need to keep it completely submerged the entire time. At least, you should.

The thing is though, the anemones will probably do a walk about in their new surroundings and most likely wouldn't end up where you would like them.

I'd combine the sand in the 55 and move everything so you have additional space for that carpet, if not another anemone.
