Could be a quite fun idea. Scope seems reasonable. Maybe add reputation scores for the important ponies? And events linked to specific reps. For example if Rainbow Dash has >= 30 rep she'll do sonic rainbooms at your events and increase awe for the guests.

Don't use flash, it's EOL and only useable with plugins
May want to look into GDevelop. Fully visual scripting, logic is events and conditions with more advanced javascript if needed, and surprisingly good games can be made with it. Free tier is fine if you're not collaborating (paid adds online/cloud tools). Probably won't be limited in this game using it.
Construct3 is better than GDevelop, but you need to pay 100$/year
If you know how to code or want to learn, use godot. Much better control and complex UI. no visual scripting
Use unity if you want 3d and don't mind their flip floppy policies

Where does the misconception that Dashie is stupid come from? She is a smart pony. No stupider than other members of the mane 6

Dashie is intellectual
