Music Man Axis MM90

Just picked up a sweet used Axis MM90.
I absolutely love the P90s, but am considering swapping one out with a P90 shaped humbucker. Looking for input from anyone who has experience (or opinions) on the matter:

• I am considering leaving the bridge P90…would a neck bucker have enough crunch?
• Leaning toward Dimarzio Super Distortion, but not sold on it…any other recommendations on P90/min humbucker/firebird pups that just rock
