Fochlucan lyrist can fit the bill. It is more Druid/Bard but that can easily work. It gets full BAB, Full Druid/Bard spell casting. It requires Evasion so 2 levels of Rogue are an obvious choice.
If you have access to Spell Compendium there are quite a few spells that can make a Bard super sneaky and a pretty decent melee combatant, Druid is also not hurting in terms of self buffing, or weakening an opponent.
A full bab combatant, with drudic buff spells, druid dd's, and Bardic spell casting, summoning animals to get flanking bonuses, sacrificing Bard spells for Arcane Strike could be pretty potent.
