Doable.... yes

The question is what are you hoping to accomplish with going with dual outlets? Performance? Looks? Kudos from the ******* Brigade who considers this derigeur with their pick up trucks???
You may screw up the performance. You would need to try to match or expand backflow, but not so much that you lose performace. Looks? Purely subjective.

The majority of backpressure in an exhaust system is in the catalytic converter. Even if you were to put a straight pipe in place instead of a muffler, you'd still have plenty of backpressure. But you'd most likely get a small improvement in top end power.

Yes...

I saw a Black MDX near the galleria mall in Cambridge, MA last week. It looked good but the pipes hung pretty low right down the center.
