I think these hang together fairly well:
Vienna Gambit a large majority of the time
French Exchange with c4
Panov-Botvinnik against Caro Kann
150 Attack/Argentinian against Pirc/KID/Modern
Transpositions into BDG against Scandanavian or just play white side of Scandanavian
Smith-Morra Gambit against Sicilian
Ok, now that actually some people are involved I'll start posting this Sunday. I'll start with the Petrov (or is it Petroff?) defence and the caro since they should be relatively easiest to handle. I'll post 2 pgn files with opening trees and then I'll be looking for input, both theoretical (suggesting better lines) and practical (suggesting overall plans in a given position or pointing out missed sidelines for black).
1. e4 e5 2. f4 handles the Petroff quite nicely!
