Welcome back Garrett - seems like you never left! Sounds like a great plan. It will be interesting to see how it will go without having a "display" tank in the traditional sense of the word. You may end up with a lot of "mini" displays instead which, when you think about it, could allow you to do a lot of things you couldn't otherwise in terms of incompatible species, custom lightning conditions etc. Other than not having room for really large specimens of fish, it could work our really well. I often wish I had the room for a series of smaller tanks plumbed together in that manner so will be curious to hear how it works out.
Good luck and keep us posted!
