@Bluedog have a look at the pictures in this post from a day after yours - it illustrates how people are using C-Beam assemblies from online stores to adapt all manner of existing routers:
I have done this myself to adapt an Ozito brand router which is what is sold at the local improvement store here in New Zealand.
If you are of the skill-level to build a maslow frame then you could probably attempt this sort of apprach for your Z automation too.
