I think having a fuge with a deep sand bed might be a big help in processing the waste. I have found deep sand beds to be extremely helpful in keeping tanks clean and free of nuisance algae, and also very helpful in keeping the alk and ca stable. The only issue with a DSB is keeping it clean, but that would be easy to manage in the fuge, and only has to be done once a year or so.
Anthony Calfo had a great thread on reefcentral about using sand in a 5 gallon bucket as an rdsb (remote dsb). If you put the dsb in a fuge, you can grow chaeto and other things as nutrient export to help keep your tank clean.
So it wouldn't really be a 'fuge, because you don't need to grow pods for the tank, but it could help your system.
