As has already been suggested, in general you should always talk with the DM about what you would like to bring into a game. Now, judging by the fact that you said 2/3 of the group do not like psionics, don't be surprised if he says that it would just not work in the game.
Not every character type works in every campaign. In my campaign, for example, psionics just would not work. Why? Because when I started the game I gave the players a survey and one of the things I asked is how they feel about psionics in a fantasy game. The group responded almost unanimously (90%) that psionics do not have a place in a fantasy game. Frankly, I agree with them.
