Well your biggest problem will be humidity.
Seeing that you're in AB I would look into a heat recovery vent unit.
Otherwise drill all the tanks and connect to one sump, make sure it's big enough to hold all the drain water during power outage.
This way you only need one piece of each (skimmer, ..).
Try to run reverse daylight in the basement tanks to help with the heating and cooling.
You might need to add extra circuit for your AC loads.
Get a screamer to let you know something flooded the room.
And lastly the carpet is out.
That's all that comes to mind right now.
