Yes, You can braze it with bronze or have it arc welded with a nickel rod

You can weld anything together (pretty much!), but the question is how long will it last? Just don't weld it to the head... :)

I didn't read the link you posted but I've done some cast welding with a wirefeed using mild steel wire with pretty good results. One was a cracked water jacket from a previous owner not using enough antifreeze. I've also done a couple manifolds including my current Turbo Ranger project.
I do like the idea of welding the manifold to the head, though.
Good luck

Sure, give the next owner of you vehicle a nice suprise... Weld everything together! :)
