Can you describe exactly what you are trying to accomplish? Why not buy a larger pump and use less electricity? At the same time, if you are running two pumps on the same sump - then yes, you could do it that way too.

You need to take in to consideration your overflow rate you never want your return gph to be greater than your overflow also are you looking for more flow or more movement ?

i run two line out to get more flow and you can if you get a SLIGHTLY BIGGER over flow tube ((not two big) i have a 1 1/4in).... i do it on my 55g 
i run to of the bigest small pumps i can lol two 900gph pumps. and put one out let on each end of the tank.

I'm thinking the OP means to have the pumps set up serially, so one pump's effluent becomes the second pump's supply (input).
Why not simply run two pumps with separate returns? Otherwise, get a larger pump. The problem with running the pumps serially is that the lower volume pump will always be your limiting factor, as the higher volume pump will never be able to push or pull additional water thru the lower volume pump which runs at a constant volume.
I guess the bottom line is pump volume doesn't "add" as you place them in a serial arrangement. You could try putting them in parallel with each output flowing into a manifold and then out a single return to the tank, as then the flows should add together volume-wise.

The main consideration is how much your overflow can handle.
You should add a powerhead inside of your tank such as a koralia powerhead to increase your internal flow rate.
