I too use half of a two car garage that I share with my wifes SUV, a riding mower, and in the winter a snow blower so I really get your space issue. Nearly all my floor and wall space is very carefully designed to get the most possible out of it included lots of mobile or take down type sets ups.
I would hate to give up my band saw, I use it for more than just general wood working though, its also used a lot to cut carving blanks. Foot print is small and its on wheels so can be moved easily.
My SCMS could go without being missed much, it has a folding stand and lives on a shelf much of the time so not that big a deal to keep it around and I have brackets to mount other tools on that stand as well so it will likely stick around. I would miss it about zero for day to day wood working though I sure would have missed it last weekend when I rebuilt our deck. My router table is bench top type and lives on a shelf next to the SCMS however has not left that shelf in 3 or so years, I have been debating freeing up that shelf space.
I dont have a cabinet saw, I do have a job site saw with a stand I made and infeed and outfeed tables that snap onto saw horses. It also lives on a shelf some of the time though is left set up probably have the time anyway. I would love a cabinet saw but in my half of a two car garage it just was not going to work without giving up other tools to getting too crowded.
Ive got a mini lathe that for a long time lived on a shelf and was mounted to a jaw horse to work. I built it a very heavy sand filled stand a couple years ago when I used it a lot. Honestly I wish I had kept the previous set up so it could also be used in the driveway in the summer, it was stable enough anyway. That floor space it looking more and more valuable by the day. I could see a dedicated carving station there with enough storage to get my carving stuff out of the tool cabinet, store the lathe, stand, all the lathe stuff and my shop vac underneath.
I do also have a full size drill press, its not used a ton but handy to have and very small foot print.
If I get rid of the bench top router table that shelf spot will likely go to a lunchbox style planer.
I also would not want to ditch my
