Yea, I'm thinking of something creativity to make some custom flags.
This is the custom flag of Equestria, or should I called "Republic of Equestria" or "Republic of Equestrian Federation"(seriously, NOT like a Russian state).
It means that Equestria is running in Republic rather than a Monarchy. So a President can rule/lead a country than a Queen, King or Princesses or etc.
The main symbol, symbolizes the two Princesses(Princess Celestia and Princess Luna) who ruled Equestria long time ago.
The yellow light shining like a sun that shines on the tip of the horn, symbolizes: Courageous, Independence, Dignity, Fraternity, and Liberty
The 6 stars positioned in 3-each on both sides of the yellow light, symbolizes or represents the 6 Elements of Harmony(or the Mane6)
The 3 colors of the tricolor flag:

The tricolour flag remastered by me,

And the shining yellow sun and the 6 stars, it's from me, I made those.
