I don't understand most of your question. For the mig part, yes a mig welder can and is commonly used to replace rockers on 02s and other vehicles. To imitate (well sort of) the spot welds, you drill 3/16" or so holes and plug or rosette weld the outer rocker to the inner one. Copy the seam welded areas you have to cut through to remove the rocker. The end result is stronger at the weld than from the factory.

Oh, now that I re-read your question, I see you are describing seam welding the whole rocker. You could seam weld the entire outer rocker to the inner as you described (leave open areas as BMW intended on bottom for drainage). If you are not interested in the benefits of seam welding (and the drawbacks) I would recommend the mixed plug welding technique/seam welding technique.
