Concerning being OCD, me thinks you don't have all your badges yet.
I have three Heritage gits with P90 and this is my take.
Unlike with humbuckers p90 do not have rings to adjust pickup height, you have adjustable screws for each string that appear REAL close to the strings and therefore limit how much you can lower the action.
This appears due to the top carve and set neck angle.
My concerns (additional) would be the lack of clearance as the strings just clear the back of the bridge and thus you could not deck the tailpiece.
The bridge has anchors that limit lower adjustment that can be removed and replace with screws. The saddles on the treble side can be filled down.
The bottom of the bridge can be filed too. On my P90 gits having similar issues I replaced the stock hardware (I am MORE OCG) with Fabar AB-1 bridges that are more narrow and thus provide more clearance at the rear and have direct replacement screws without the anchors.
As you love everything else, you may want to work on some fixes rather than exchange and hope the replacement is perfect. As these are mostly handmade, neck angle and top carve will differ.
Good luck!
