The answer to alignment issues may be make something similar to my base that has a flange that seals to the hood mounted air box. You can lay a layer of stretchy saran wrap or similar over your 8 stack set up, then glass it. Once cured, just lift if off the 8 stack and reinforce or add a flat flange.

I've made many small fiberglass parts like that.

I can see it being a challenge to line up a box with 8 holes on the hood. Having 2 boxes, one with filter and one that just seals to scoop would be cool, and easily swapped.
