I am not a hydrolics engineer, but it seems to me that the mag12 would impede the performance of the mag9, presssure wise.
Why not just plumb them individually? Better yet, why not have 2 mag12, plumbed individually? You would get a better flow. You could always use your mag9 on a DIY beckett skimmer.
HTH
Edit: Even better yet! Why not get a single mag24 or mag36?![]()

I've tried it with an Eheim 1250 and a Rena XP3 filter. It cuts the flow down some but not to the point of being better off without one or the other. I had to do it because at the time, I only had 1 hole through the wall for return water.
I would bet that with the 2 tees, you're going to lose A LOT of flow to all the internal turbulance. You'll get the most flow by plumbing them independently.

Worked at a store where we did that with 3 mag 36's. It worked GREAT until one mag went down. As per your drawing, it won't work well. Water would rather go straight than turn, so the water from the mag 12 will want to go into the mag 9 pipes rather than up. It might be better if you had the mag 12 running straight up and the mag 9 running into that pipe.
Something that may help is have the piping for the mag 12 and 9 small and when they join, have it be much larger, so its much easier for them to go into the one pipe.
Best option would be have them individually.

Is it bad to have more flow on one "side" of the tank then the other "side" of the tank???

no need for that much flow going through your sump. use the mag9 for your return and use the 12 for a closed loop.

You don't have the big ol' MaxiJets hanging in your tank. Other than that, put them on a wavemaker and you pretty much have the same thing. Of course you could use an Oceans Motion and divide it up even more (without losing flow like you do with a SCWD) which would put you ahead of the MaxiJets.
