Are the TWO fleshly bodied 1/3s of the Godhead the same in substance?
The Godhead is three personages, one in heart, might, mind and strength. Three become one, and hopefully we become one with them too, at least that is the plan and the purpose of the atonement.
BTW, atonement -- at-one-ment: to make one with God.

Was that a YES or a NO?
