Unless it was part of the Second Origin process (and whatever Gajeel did in his training), unlikely. There's a reason that Jellal was surprised that Sting and Rogue could enter Dragon Force on their own
, Natsu (as the only First Gen. Dragon slayer to go into Dragon Force) had to force himself into Dragon Force by first consuming Etherion, then consuming Jellal's Flame of Rebuke. No other Dragon Slayer had shown the ability to enter Dragon Force without some outside help.
