Haha I was going to reply sure if you supply the parts for my truck. Then I read you user name and realize who I was taking to... You'd plop this on your truck and put 20+ pounds on it for sure.
I've got an extra intake that I'm going to clean up like this one. Then we can test that one. Maybe I'll stick it onto my Camaro to test it with boost. It's about time to plump the turbo on it.

I've made a ton of ABS repairs like this and it is very strong. Ive learned, just like real welding, a stronger joint is created by having filler material. I used scrap ABS pieces cut in strips and used them sorta like TIG welding, heat both edges plus the filler and while they are all hot swirl them together. I have had very good luck doing it. However, not all "plastics" take to it. A urethane (guessing) stock Camaro bumper cannot and will not fuse together like ABS plastic will.

Another tip for the ones who want to try it, repair both front and back if you have access to both sides. I have literally fabricated from scratch 3 dimensional brackets and stuff using sheet abs and patience.

Never saw this thread until now but looks very nice. I did this for years welding bulkhead fittings and sling/tie down/lifting ears to tanks and the like...pvc, poly, abs etc. You want to chamfer the opening just like in real welding and then begin begin a solid bead around it. The size opening I created is what dictated how many passes I would make, usually creating a pyramid type weld by stacking one pass on the other and working my way out and up. That negated the possibility of leaks and increased the strength. It was similar to making root/hot/cap passes in real welding.
That said, the only thing I would be leery of when using a soldering iron to do your welding (as opposed to a pricey plastic welding gun/correct rod) is the uneven thickness of the weld. Beveling with the addition of a tight fitting plug with your method would probably net very close results to a proper rig though, with the material finding it's way evenly to the bottom of the channel. In either case, the results make that intake very appealing to eye and was worth the effort. Best of luck should you throw boost at it.
