Would you play in a "Sicilian Defense" Tournament

For a local chess club, I am looking for ways to make things not always the same old stuff.  When there's a tournament available every week, interest wanes.  Some obvious ways to create novelty are to vary the time limits, or the formats (Swiss vs. Quads, that sort of thing), or to play Chess variants, although some people think that Xiangqi isn't so much a game as a heresy, but others like it.

 One thought that occurred to me was to hold a "Sicilian Defense" tournament.  In this tournament, the game starts with a required opening.  So, basically, the game starts on turn two.  White must play e4 on turn one.  Black must play C5.  Obviously, you could also do a "French Defense" tournament or a "Ruy Lopez" tournament (two or three turns specified at the beginning), or whatever sort of required opening was chosen for that tournament.

 The purpose of such a tournament would be to get people practice with a particular opening.  For example, I want to practice against a French Defense, but I can only do so if someone plays it.  If there was a "French Defense" tournament, I could be guaranteed that would would happen.  Obviously such a tournament would not be USCF or FIDE rated.  It would likely be fairly small.  It probably wouldn't attract grandmasters.  We can assume that the entry fee, if any, would be small, 5 - 10 dollars at most, depending on where you could get a low cost sit, and prizes, if any, would also be small.

 My question is would you find that sort of thing interesting enough that you might spend a Saturday or Sunday afternoon doing it?  If you saw it advertised on the web site that listed local tournaments, would you consider going?

ETA:  I should add that I'm interested in this as an OTB tournament, not online.  I see from some posts that there are threads devoted to starting some required opening tournaments already.
