Well, not exactly, no.
Just so this doesn't continue: http://www.starwars.com/databank/character/asajjventress/index.html
Well, Shaak Ti's quite a good Jedi and Stass Allie's above average so I'd say they should be able to do this. The two of them together are probably about equal with TPM Qui-Gon and Obi-Wan. Those two together were able to defeat Maul who, IMO, is stronger than Asajj so these two could probably beat Asajj.
