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?

Stock used Magnum cams are plentiful. That is the best way to do a regrind, as long as you not looking for something “really big.”
What kind of application are you looking for intended use?
