Actually, they can't do Windows on mainframes... VM and MVS, sure... But Windows hasn't been ported to that architecture. On the other hand, Red Hat Linux has. You should see it run on some of IBM's "big iron!" I saw one implementation where there were 165 VMs all running RH Linux! Awesome.
And speaking of R&D, IBM has been doing all sorts of R&D in conjuction with Red Hat, just like DEC and then Compaq did with Microsoft, before MS abandoned the Dec Alpha. In fact, that's exactly what SCO claims, except they claim that the code was stolen.

I don't see any reason why anyone would want to, either. There's sufficiently other H/W platforms for Windows that perform at the top of the TPC.

Distributed network resources and servers have always worked better for us, not only because of the quantity of clients (several thousand) but because of the diverse set of applications in use.

Not really that similar, since Microsoft didn't go partner with another vendor and use the Alpha designs in the new project.
