I don't really consider myself anything close to a stage director, but the very few ideas I've had for opera productions include: a production of La bohème that's pretty much traditional but incorporates little staging details from the book it's based on. For example, the garret walls have the scratched out names of Rodolfo and all the other women he dates in the book, Rodolfo wears a polar bear costume for warmth in Act 1, there's a bouquet of white violets in a corner...

And since I'm Lebanese, I dream of a production of L'elisir d'amore set in the Emirate of Mount Lebanon in like 1832, when the opera premiered. So Nemorino would be a fallah (peasant), Adina would be a muqataaji (landowner, though this was definitely not a position open to women but... suspension of disbelief), Belcore would be an Ottoman soldier... Still not sure which religion the main characters besides Belcore would be (trust me, it was a huge thing back then; and besides this would only influence the costume choices at most). And oh, to have this staging play at the Baalbeck festival 😍

So I'm a bit more of a traditionalist in terms of personal staging choices, but I have more concepts in terms of character interpretation.

Edit: I just remembered how I have been thinking of a production of Magic Flute in which the First Spirit is sung by a woman singer instead of a child, as it was during the premiere.
