Any Unlock all faction mods for RTW?

I actually have a question of my own though, if I was to put the roman senate under playable what would happen? I'm guessing it wouldn't let me play as them issuing missions and such?

You can indeed play as the Senate, but I don't think you can issue missions on your own (I tried it a long time ago). Also the "Senate" tab doesn't work properly as the game is not made to include playing as the Senate, so if you hit this tab, your game will ... Also I believe you will lose that game anyway, as one of the winning conditions for a Roman faction is... eliminating the Senate and conquering 50 provinces (a bit hard to accomplish these conditions at the same time).
But you can play the game, just conquering other factions/provinces, yes.
Maybe I should set up another SPQR campaign, just for fun...

Yeah watch out though when playing SPQR, they tend to go into debt within a handful of turns.
