Gutobo: Recon Open: Target a Province. You have Reconnaissance at its battlefields. Before this turn ends, bring into play each dead Goblin Personality you own who was destroyed this turn during a Combat Segment whose battlefield was at that Province, ignoring Gold costs.
If Gutobo's ability targets a province, attacks the province, and then is subsequently destroyed at the same province, during the combat phase, is the following sequence legal? Gutobo's owner recruits Gutobo Experienced and before the end of his turn, returns the original Gutobo (non-experienced) to play, ignoring costs.

Yes, that's completely legal. And sorry, I'm not entirely sure why you might think it's not, so I'm just going to have to guess at my explanation here:
Even though Gutobo Experienced has the "Unique" keyword, his basic version doesn't. Unique only prevents you from controlling two cards with the same title if they BOTH have the "Unique" keyword.
