Have you considered a rounghing mill to rough first and then use a
normal mill to finish? With some of the TiAIN coated roughers you
MUST increase your feeds by something like 2X that of HSS or the
cutter will not work. Of course you need a very powerful spindle and
powerful drives, but if you can do it you'd get your work done a lot
quicker.

A very cheap tool changer is your hand :) If you seriously need one,
I'm sure it would be fairly easy to design one, given the automation
control to run it.
