So realistically, could I home at 60 IPM?

For stage 1, no problem. Assuming EMC rapids to the home switch then backs
off at a lower speed. IIRC, my rapid is 100 ipm, back off at 5 ipm, find
index marker at .5 ipm. I nearly always "park" the machine on home at
shutdown so homing takes maybe 15 seconds at startup. I also save part home
as the back left corner of the vice - one less step to do toward making
chips. You can be clamping your part in the vice as the machine finishes
homing. or you can be typing in your gcode. I hate to wait on machines
