Stacked nano tank idea

[reefsquared]

I have three tank ideas. I am doing a sps tank, an acan tank and an anenome tank. All three tanks are the same size and drilled. They are 24 by 14 by 14. Instead of having tree separate stands and sumps. I was thinking of doing a stacked tank idea with just one sump. Any thoughts on this idea?

Im running 3 20L and 1 is for the sump. works for me, love the setup.

Ive done plenty like this but not with three different types of corals/inverts not sure its ideal.

My other concern is how to stack the tanks so that it looks nice
