Turkey baster the old fluid out of the master cylinder until the "min" mark. Then pour new fluid in and bleed as normal, but stay at each caliper until it bleeds clear fluid. I think the fluids won't really mix is my experience. I have upgraded to the Motive Power Bleeder (linky) which I fill with fluid, pump the pressure up, then crack open a bleed screw and leave it open until it runs clear.

You can actuate the abs system with a Honda specific scan tool. Helpful for bleeding the entire system including the abs unit.

Or find a diet road and slam on the brakes a few times is how I do it
