shaving the drip rails is always a cool mod. gotta think about rain coming in tho. they're there for a reason! you'll need to either think of a new rubber seal or make your roof come over the top of the door so the water won't leak in.but yeah you've got the right idea, cut a few inches, tack it a few spots(because the gutter is where the roof skin is attached to the door frame), cut a few more inches tack some more until you've got it all tacked together, then go back and fill in the spots between the tacks until its fully welded. you'll want a wire wheel to clean all the crap tho. rain gutters are a dirty bitch.
you just don't want to cut it fully off before tacking it together, it might separate.
