Is that a picture of your bike or what you going to do your bike like. I see the picture has it all painted up nice!
I tested out a replacement regulator for my MIG welder yesterday and tried welding to some test pieces. The kiddy bike tubes on the bmx style handle bar cross piece I welded some channel steel to it. Next I am going to make braces for some heavy duty training wheels for when I add an art cover for my motor bike I'll use in parades. I guess brazing is usually used on the frame tubes, but the MIG is all I have so I'll be using it.

It may not be what you want or have room to work, but maybe?
If cutting out the frame portion and welding back in a new section can be done by you or economically some how, throwing out the frame would not be necessary. I've welded a bit, but not brazed or used a torch. My MIG has some limitations.
