Wiring multiple charge controllers.

Is it possible to wire 2 solar charge controllers in parallel to one battery bank? Right now I have 2 solar panels of different wattage. One is 250w and the other is 175w. Right now panel #1 goes from its charge controller to battery bank #1. The other panel goes from its seperate charge controller to a different battery bank (#2). In short, I want to wire the two charge controllers to go to one battery bank. Is this possible? I hope this all makes sense.
