Well, much smaller countries than Georgia come up with good stuff so I don't think it's impossible. They started out with one of the imo strongest debuts in the contest back in 2007, and that song was original, had a good presentation, blended local motives in interesting ways and stood out in the right way. Why not a jazzy deep house ethno entry? It could work in the right package.
The problem now is that they misunderstood the "being original part"-concept, because what does it help when their entries are badly produced, bland and forgettable in the end of the day? Most people use their entries as coffee breaks

At least they should be remembered if anything, but they can't even achieve that so just chasing originality for the sake of originality isn't working.
I am a strong supporter for originality, but
if Eurovision Georgia would be a person, it would be that pretentious hipster studying a dot on a painting but actually in reality know nothing about art. Like you said they need professional guidance here, but I think they also need another team running this because again it seems very much a "one man's vision" and that vision is clearly wrong.
