About the setting of a play

Hey there! I was thinking of attempting to write a play. I’m 18 years old I do have some experience with writing short shorties and I even wrote a screenplay using Fade In software in may this year. As for theatre, I’m a big fan of opera.

Anyway for some time I had an hour idea for a full-length play set in the Heian Period of Japanese history where the main character would be Abe no Seimei. I wanted to ask if it would be a good setting. I’ve noticed that most plays after the 19th century are mostly in realistic settings (Example: “A Doll’s House” by Henrik Ibsen).

What do you guys think? Would it be possible to stage such a play?
