That's quite an unusual question. A far as I'm aware though, no, I don't think Doom uses that sort of transformative magic. Even falling back on 'super science' Doom isn't really into forced mutations. Why send a man when a Doombot will do the job just fine?
In terms of magical ability Doom uses it more to supplement his armour's systems, energy blasts or shields etc. The other major use of magic that Doom regularly employs is various forms of clairvoyance or foresight, the ability to see the future in all its different possibilities.
