Maybe you don't need to, since you will get Imoen later.
If you want an Archer, get Mazzy.
If you want a tank, get Anomen, who can cast darn good clerical spells too.
If you want a mage, either wait for Imoen or get Nalia.

Be careful, Yoshimo will leave your party later.
Maybe dumping Yoshi now and picking up Jan might be considered.
