They'res to many to name, but I'll try to name most of them. Honestly, most Mages can be played as support, though I'd only do it as a support if your adc is your friend. A decent amount of junglers can be played in top lane as well. Also as for Mages going top, my friends and I all think that out of the normal mid lane mages, only mages who build RoA should be able to go top. Obviously mages who are normally top laners are alright for top as well. Also sorry for the weird format, I didn't want to just have all of the champions create a long post so I put most of them in a 2 per line like this.
