Transistor LC filter based graphic eq

Hi guys,
I have been asked by one of my costumers if I could design a 12 band graphic eq with discrete transistors and LC filters.
I believe that discrete transistors aren't the best solution in this case but he was pretty sure that he wants to use them.
I came up with a basic formof the circuit but I would like some feedback from you if some of you have any experience with something similar of if you think that it is good Idea.
Thank you very much.
