I don't think allowing a weapon attack as a minor action is a good idea. Brawler Fighters need some sort of benefit with their powers over other characters. It's their schtick; their powers allow the attack AND the grab all at once. Allowing non-Brawlers to attack in the same turn without spending an action point - even if that attack is limited to an MBA under limited circumstances - treads all over this.

That's why I feel the attack itself needs to be a standard action and the grab needs to be a modified "minor" action of some type. That will allow you to make unarmed attack if you succeed but will cause you to lose your ability to use a standard power if you fail.
