Thanks fellows.
I contacted Revolver Supply Co. in New Mexico. George there replied they could do a run of thinner .032 material (using his existing die) as long as their S&W 45 pattern will fit into the Ruger cylinder correctly.
I accepted his offer to try a sample of his product in my Redhawk which I should have in hand next week to hopefully verify it will drop in nicely in my particular gun.
Please feel free to contact him and express interest.

They charge approx. $0.55 to $1.20 per clip depending on quantity for S&W 45 cal. moonclips, quite a savings vs. factory.
