Alvarr would make an excellent returning villian, but I(as the only one in a million) think that Gilli should come back like an apprentice to Merlin or something. I never thought of him being Galahad before... that would be excellent! Gilli would make an awesome sidekick on a quest with Merlin, it'd be really cool to see them together.

I also want Freya and Hunith to come back more often so we can have more female roles. There could be a way to ressurect Freya, since we don't know for sure that Igraine was a hallucination or not in Series 2, after all Merlin is the most powerful warlock ever, so he could probably pull it off if he tried really hard. As with Hunith, Merlin could make a lone journey to Ealdor to visit her. Obviously some conflict would come up in that episode, and maybe we could learn more about Merlin's childhood.

Cornelius Sigan would make an AWESOME villain. Mordred could summon him and give him a new body(maybe Alvarr?) and they would both work together to get Merlin and overthrow Camelot.
