Yes that should work fine, especially if it is a little over a foot wide in the X axis I would love to see your set up when it is done! Tips for decorations, flat hides get slate from a local aquarium store and get cork flats from a local exotics store, get like 5 flat hides than a piece of drift wood spanning around maybe half the tank with some fake foliage, this will give them ample hides and lots of space to explore and weave them selves in and out of. Leaf litter is good too as well as moss. Another tip, tong feeding will work best if you have the ability, you can monitor that all of your tigers are eating the same amount and if they don’t want to eat.
