Have you considered a flip up tablesaw like thishttps://www.youtube.com/watch?v=XaeZ17O_MEI
Someone here has done a nice job of it and made nice HDPE casters for it
I think he may have used a heavier machine than that in the video.
I would want an induction motor personally
On the bay, I recall seeing an old makita (i think) that was a really industrial wee thing
that's what I would look for,
I'd say it could probably be done with the ts200 or 250 if you welded a nice frame up
