Batman was Green Grenade's sponsor for Hellfire, he was leaving for vacation just before the reboot but he'll be returning. Another option could be the Ted Kord version of Blue Beetle, who had his own Kord Technologies. You don't have to have a stealthy mentor, or be like your mentor in any way if you don't want to. Ditto only has the whole being alien and looking human thing in common with Superman.

Actually, I chose Blue Beetle as my sponsor when I removed Hourman. The name was changed to Time Bomb, btw. Is that all good, now?
