I heavily contemplated this when I put the 3.8 in my car. Less about HP gain to me, and more about just getting rid of this mess of a system.
There are plenty of parts available from various hot rod catalogs to do this, I just decided at the end of the day to leave stock well enough alone.
What I think is would be really nice, as well, would be to go to an electric vacuum pump for the brake booster, again, mounted up front. I do have a tandem pump on my 3.8, which provides brake vacuum mechanically instead of "stealing" from the engine, but I'd love to see the only lines from front to back be fuel and coolant.
