It seems like mikep had a good solution in a reply to another post (Bolting to solve Bow) but it appears the bottom of my cross straps are even with the bottom of the foot nut.
I’ve torn half my machine apart this evening and at this point I feel like removing the adjustable feet and replacing the middle baseplate M5x25 bolts with longer ones and fastening into my table top may be the only way to fix this.
