I would say to keep it simple, make it the best version of itself that it can be.
With your collection, you've got better options when it comes to higher powered packages than the AU if you gave it the same potential output.
What that means to me is a mild stroker. Celebrate and champion what it is over making it what it isn't. Something in between a T3 type setup and where Tim ended up with the AU racecar before starting on the BA project.
