front floor support brace can this be welded?

[wazzabie]

I'm replacing the rockers and inner rockers on a k5 blazer. Part of my front floor support was rusted so I cut it out. I'm trying to patch the floor support. I've welded in a small patch as show in the photo and have a larger piece to complete it. I'm debating if I should try to save this or go with a new front floor support. My concern is getting into the joint and getting things misaligned. Your thoughts? Is patching this floor support going to work? Also if I decide to take the front floor support brace out what is the best way to remove it?
