150cc GY6 carb upgrade too big - HELP!

I have a 2011 GY6 powermax 150 (VIP) that I bought used as a fun project. Ended up buying a 30mm carb (upgrade from stock 24) and a new intake manifold. Problem is even with 1/4" rubber spacer it doesn't fit nice (back of frame would hit carb when flexing). I have been considering my options, and have come up with two. Basically, I wanna run these two by the community and see what you guys think...

Option A) put a 31mm riser on there and then use a 30-45 degree curve of hose to go off to the left a bit (1st image), with a straight in air filter instead of filter box (which I dont like because of limited room there for air filter, and its still dangerously close to the bottom half of frame when rockers get compressed)

or B) this configuration (2nd image), with a custom made bracket to secure the carb to upper part of frame and keep it level (and from bouncing too much) But my concern is that in this option, even if I cut a couple inches off the ends of that hose, it would still be too long (???)

and of course option C = having something fabricated or getting one of those super high like 5" risers but then, (as with the 30-45 degree angle idea) I am in danger of running out of clearance under the seat bucket...

This is my first scoot, but I once rebuilt a 79 chevy van and have always worked on my own cars/mowers/etc so, while I may not be a mechanical genius - common sense tells me the path between carb output and piston head should be minimal traveling distance for optimal performance... Hoping you guys with more experience rebuilding scoots can offer some insight, here.

Those of you who would flame or bash my post, please remember that there was a time you didn't know jack, so I respectfully request you save the smarta$$ comments. Thanks in advance, to those of you who do have constructive feedback. I am glad to be a new member, as I have found a lot of helpful info/people here while trolling other threads. and I have also been having tons of fun working on this thing and have had several opportunities to implement some of the invaluable info I have found on these boards. Cheers!
