The only way I can think of to do wheel of time with DND would be to have regular magic and the big stuff be ritual casting or require a sangreal or similar item. Also you'd have to assume that all PC's are taveran or fate touched so reality bends and shifts in attempt to force Thier destiny. But really what you need is an open system where characters gain levels in specific types of magic and start with a certain level in Thier talent. And roll all magic checks as skill checks, with DM arbiting the actual affect vs player intent depending on role
