Probably would be a good tool to have going forward.
What is the maximum tilt degree of your table saw? This angle I'm looking at in your drawings shouldn't be more than 60 degrees or so I would think (which is a 30degree angle on both pieces).
If it is 60 degrees and you can afford to do it, put another piece of plywood on the Shopbot and run a thru-cut profile path with a 60 degree Vbit cutting the pieces to the size they need to be (or leaving it a little proud and then rip the square edge down to fit with the table saw.
