Air cleaner vs hood scoop

[70XR7]

Either way.. i'd still like to get this setup.

I'm just worried about the cut. Would I need an oval cut? Could I do it with a round cut somehow so I could convert back in the future if I wished to a typical round air cleaner setup?
I know it's the whole square peg in a round hole argument.. but just wondering if it's been done..

... unless I can find a round one. ffs. I think i'll just stick with round.
I like those valve covers though..

I like the look of the oval air cleaner, but don't cut into the hood unless you are going to reverse the scoop as noted above. but the oval ones looks awesome.
