Interstate 75 multiple different sized panels?

Anybody running an Interstate 75 with more than one LED matrix?
And if yes, are they different sizes?
I have planes to run a 64 x 32, and a 64 x 64, maybe even two 64 x 64 and a 64 x 32.
64 x 32 4mm pitch (64 wide by 32 high) for viewing from a distance.
64 x 64 2mm pitch x 2 side by side for viewing close up.
All on one Interstate 75.
