I think you plan works just fine. How are going to make the cuts? In my mind a simple sled, or jig, for a table saw does the trick.
I'll bandsaw the cuts with a 3TPI blade, then 'joint' using a bottom bearing 1/2" straight router bit against a clamped on straight edge. Can't use my actual jointer, unfortunately.
I've owned at least six tablesaws, from my current $129 15 amp, 10 inch to a 7hp 16 inch, 10 foot slider with 5 inch scoring blade. I much prefer the bandsaw and a jointer for instrument work. I make rough crosscuts using a 7" circular saw or Bosch jigsaw if necessary. I haven't used the table saw in years, it has a 2'x8' piece of plywood clamped to the top of it, it's my main workbench. Maybe if it wasn't so underpowered.
