You have to remove it all. You cannot just have the fronts and not rear as the ABS computer would sense a problem and disable everything and give you a warning light.
I did this same swap and removed all the ABS sensors, pump and fuses. Here is my quick write up.

Don't cut the wires, you should be able to unplug them under the rear seat or somewhere near there. Then just cut the cable ties and unclip the clips holding them to the brake line and you should be able to remove them easily.
Removing the ABS relays will disable the ABS and turn off the ABS light on the instrument cluster.
The ABS plumbing and wiring can remain in place and the brakes will work normally.
One thing to note, if you ever swap the MC or let the fluid run dry, you will have a heck of a time bleeding the ABS pump. In the FSM, it specificlly refers to having a special computer hooked up to cycle the ABS pump to bleed the system. Without all the sensors working, I doubt you will get any dealer to do this.
I didn't want to screw around with any of this and removed the pump, sensors (yes, unplugged them), removed the fuse/relay under the hood and the fuse under the dash. No lights, codes or whatever and no worries with bleeding the brakes.
YMMV
