if we win it don't make problem for sgtool verification? and for rule steamgift?(you can create ticket to support for add game!)

You could just offer the game in the giveaway game list by creating a corresponding ticket.
P.S. I also had such problem with this game here :)

You can't give a different game name. It's in the rules. You will get soft banned. You can request game name if it's not in SG.
