I think you'll find that buying an MFT with the intent of mounting a CMS TS module to it will be an expensive and frustrating experiment.
The MFT($600-700) plus the TS module ($400+) already puts you over $1000 and you'll have an imitation of a tablesaw with a really frustrating fence - no micro-adjust, repeat cabilities, ease of squaring, etc.
You would need to spend another $400 or so to get something like the Incra fence - and then some way to attach to the MFT like the precision plate(another $100+).
This also doesn't consider the $500 plus invested in the TS that you'd want to dedicate to the module. It's not quick nor easy to mount the saw in the module and imprecise if you want a bevel.
I say this as someone who had a similar thought, but with the actual CMS-VL, and thoroughly researched this experiment.
I now have the MFT/3 and CMS-VL(no TS module) and I'm super happy with the setup. I can easily do thin rips on the MFT or use parallel edge guides for longer pieces.
I guess what I'm getting at is asking what are you trying to accomplish and is your proposed idea the best way to go about it?
If you need quick rips with portability there are lots of tablesaws that would be quicker and easier to use for the same or less you would invest in the MFT with dedicated TS module.
If you don't need portable and have some space you can get even better tablesaws for not much more money.
I do think the CMS-VL with router is awesome. So easy to use and setup and comparable to building your own router table.
The TS module for the CMS just feels like way too much of a compromise in utility in exchange for portability and the 'system' use.
