Why not try something similar, but opposite: squat 3x a week, but go heavy/light/medium. Do DLs on light squat day, just 1x a week. Fit Bench work and additional lifts where you feel it would be good.
Either that, or basic Westside, where you would rotate between ME SQ/DL every other week. Tate's "The Eight Keys" should give you plenty of ideas.
