Hydraulic cam core Used for a.roller regrind?

As the heading / question suggests. Can a flat tappet hydrualic cam from an LA be used as a core to make a 360 magnum roller.cam?

Aside of actual lift, duration, etc... details. I'm curious if the flat tappet lob shape can be reground for a roller lifter?

That would be a no. There would be no material left/available to accomplish this. A few comparisons. Flat, next a roller. FWI. that roller was overkill.
