I looked over it very quickly, but why aren't you doing it in 6/8 throughout? The implied 3/4 measures have always read as syncopated measures to me anyway...
I did it this way because the book I copied it from had it with alternating time signatures. Like you, fidhle said just writing it as 6/8 throughout and leaving it to the performer to notice where the accents are falling might be least confusing. (And he pointed out that the dual time signature looked like 36/48 instead of the intended 3/4 6/8.)
He also gave me a clue to where I'd seen that double time signature before. He asked whether the tune is Spanish and pointed out that this pattern shows up in other Spanish music, then hummed a bit of "America" from West Side Story. When I looked it up, I saw that "America" also bears a time signature like this (but the other way 'round: 6/8 3/4), so that's likely where I'd seen this notation.
