I've been looking a little at this from the 1c4 white side. I think if you play against an opening hell bent on a kingside attack you have to be patient...and not expect an immediate exciting game from your own point of view. I just confirmed that from the database after 1e4 c5 2Nc3 Nc6 3g3 black is scoring 55 % to white's 45%. Very respectable.
The queenside opening/defences IMO need a certain inscrutability about them. There's a certain "rope a dope" aspect to the play I think. You could go for more immediate gratification of action with less good results.
I've played a bunch of games (as Black) with something like e4 c5 Nf3 d6 Nc3 Nf6 d3 g6 g3 Bg7, etc. Mostly push on the Q-side, same side castling. Sometimes ridiculously symmetrical positions. I've also tried developing the bishops on e7, e6, and castling.
This seems boring; I would like to liven up the closed Sicilian! I'll consider anything -- even down to a Fred Gambit approach ;)
