Longest Opening Repertoire

What is the longest Opening Repertoire?

A search is on can you beat this?

Would you consider kings pawn to ruy lopez a valid transposition?

e.g.

1.e4 1.e5 = Kings Pawn

2.Nf3 Ktc6

3.Bb5 = Ruy Lopez

3..Ktf6 = Berlin

4.Ktf3 = Spanish Four knights

Therefore it has a transposition count of 4 and not 3.

I think the Catalan/English/Reti could be a good place to look

Starting with g3 as the barzca attack!?

We look forward to your input.
