2 filters and external pump connected together?

Is it feasible to connect 2 external filters and an external pump together through a manifold type arrangement for return to two bulkheads in drilled holes in the bottom of a tank?

Two eheim (2073) filters and an external pump in closed loop from 2 drains and 2 returns in the bottom of the tank. The pump will provide a separate loop through a CO2 reactor. Is it possible to connect the three devices 2 filters through a Y plumbing connection, and then that into a 4 way connector together with the 3rd pump, and then the two outputs from the 4 way to two bulkheads in the tank base? The idea is to mix temperature and CO2.

Obviously I will put one way check valves on the output of each device to prevent one pushing into another. My (sorry uninformed) question is if the three pumps have different pressures, does that matter if they are connected in a Y and X fashion with one way check valves? Would a higher pressure from the standalone pump interfere with the output from the two filters (given check valves)? In flow terms and mixing would this be counter-productive or inefficient compared with plumbing separate returns to each bulkhead?

I would not do this. Each filter was designed to work without other pumps (or filters) in line with it.

I would run each filter separately through its own bulkhead, or one filter could return over the side and run the pump through the other bulkhead.

Try to aim all the water coming into the tank in one unified circulation pattern. Do not criss-cross the inlets.
