I would say you're going to have some very strong flow on the short distance from back to front. But you can turn the pump power down until it's what you want, so yes, this can be done. Two would cover a 36" long (wide, in this case) tank just fine.
I think they are best placed at opposite ends of the tank. They produce amazing random flow when two of them are opposed that way. But if that's not a good option for some reason, other arrangements can be made to work very well, especially since each pump is separately programmable. They do move a lot of water.
