3.5 swap?

Definitely not to scale just off the top of my head kinda thing. What do you suggest?

I would have to know the size and shape of anything that was gonna hang in that area first. I think it's a cool idea...and the right size stock would be strong enough the way you have it laid out. Maybe look at the charger under chassis as a guide to go by.....hell, you might even could frankenstein the two together....IF they are made that way. But I am unfamiliar with them.
