None of this seems really necessary - the research I've been doing implies that 1 micron (10-3 Torr) is enough for a pump-down and that should be achieved in just a few minutes.
I can see the need, just maybe, for a TM pump if working on an industrial scale (or if someone gives you one!), but assuming at best I need 10-4 to 10-5 Torr, I'll stick with a fairly normal molecular diffusion pump and suitable multi-stage backing.
