Need to rough some 55HRC Steel and beat the 28minutes EDM quoteRoughing suggestions please.

Maybe a 2D dynamic toolpath???? But man...I don't think that I can beat 28minutes. I know that its going to spring some to so I'd have to stop to re-clamp.
I've seen ceramic inserts to some pretty amazing stuff in inconel. If I could crank up the R's and plunge with some kind of .250dia ceramic cutter at a crazy feed rate of 40-60ipm, then 2D HFM the rest.....
Any suggestions? Heres what the part looks like with the stock drawn around it:

Keep in mind that the wire EDM is going to stack the parts up, so the real cycle time might be more like 4hr to do 8 pcs.
We've had great luck cutting starter gear teeth in flywheels over 70Rc using AlCrona coated endmills, using straight oil.

28 minutes is a bargain, depending on the thickness.
