The reason I'm asking these seemingly annoying questions is that once I understand your intentions - which as you avoid answering my questions I still don't - that I can give you further advise like the OEM crossmember is actually strong enough in most cases. This as substantiated by chassis engineers that design cars.
So if you broke yours, which you avoided that question, it would be interesting to know why. Seeing as it's already, according to engineers that design cars, strong enough.
Good luck tho.
