Sump 10x bigger than display tank ?

[Acipenser]

I am just wondering if any one has ever seen a set up where the sump was in say a basement or crawl space and plumbed upto another room in the house to one or two display tanks?

I ask because I have a huge heated concrete crawl space under my main floor that I could easily fit a 100 plus gallon sump/refugium into, but have limited space for display tanks because we are in a town house and I share my space with my wife and Kids.

I thought about setting up previously when I was into breeding cichlid's. there is every thing i need already there, it would be so easy to add a ato/ro. I could have a 75 gallon refugium it would be awesome.
