maybe it would be possible to do your sump into the next room over? and do something in there keeping your display area really clean...
if not you could do a cool mangrove terrarium field type thing next to your tank
here is a pic to give you a general idea but this is a really really outgrown version of what I was thinking... (and you would still have to hide your mechanical filtration somehow: Skimmer Etc)
Or You could always nicely encase a sump and turn it into a bench or something as well and just keep it on the floor near your tank I've seen that done a few times as well
