Since you don't care about damaging this rotor a flywheel puller should work, I would use a nut or something on the crank end to avoid wrecking the hold-down bolt hole.
Using the rear axle as a tool should work too, you just grease the threads and screw it in the centre of the rotor (after removing the 6mm bolt). If it turns in less than 4 or 5 full turns before bottoming, I would be careful - you don't want to strip the threads off the axle. The actual Honda rotor pulling tool is hardened steel and doesn't have the pointed end like the axle... so it's stronger metal than the axle and uses more threads.
