While I applaud most cases of fan made class designs, my only response to this is; OH HELL NO!
Time themed abilities and armor are the only hope Mages have of getting a distinct "flavor". There is only so much you can do with fire and ice. Timewarp, Alter Time, Temporal Shield, Timelord's Robes, Chronomancer Regalia... the list goes on.
Warlocks can go mess with the Shadow and Fel. Let Mages delve into the mysteries of time itself. (Cue Dr. Who theme song)
