I will 'fess up' to being an owner of something like what you are describing - sort of...
Basically I bought an old Festool basis table cheaply from ebay a few years ago (it is the precursor of the modern CMS with side rails the same as the old style MFT). I got a jigsaw mounting plate for the Festool trion jigsaw at the same time which is absolutely great for cutting small pieces very accurately - for anyone following my current writing desk WIP
https://www.ukworkshop.co.uk/forums/writing-desk-wip-t38747.html I used it to cut complex angles on the four legs which would have been difficult to do any other way that I could think of.
Then I was 'given' an OF2200 router for some work and as a result I bought a new CMS router mounting plate - this is now my router table and this is the default that this table is set up for. It is such a solid, dependablt set up and is almost spindle-moulder like in the ease of use, stability and reliability.
About a year after I got it I saw that Rutlands were selling off a sliding saw mounting plate for the Basis - this was for the ATF55 saw rather than the TS55. It functions in 2 modes - as a table saw with a mitre gauge, fence etc - but then it really comes into its own as a sliding table saw - this is fantastic for the control that it gives you and I do not own a SCMS because of having this sliding saw.
So, for about £1000 all in I have a very portable table saw, router table and inverted jigsaw. They are irritating to swap over but in reality I rarely have to do this - only for 'specialised' jobs.
If you are interested I will happily do a formal review of it - I have not done so far because the sliding saw module is not now available for the CMS - I think this is because Festool want to sell the precision saws which I believe are sliding themselves.
Hope that helps...
