Making a room sound "live"

Hi All, After years of recording in a bedroom with carpet and other absorbent materials I finally have a chance in my new location to make a better sounding room. The room itself used to be a bedroom but it has a mantle which runs around half the perimeter as well as a closet which I removed. Overall this keeps the room from being a perfect square which I hear is helpful. Last night I tore out the old nasty carpet and once I finish sheetrocking I will start adding a hardwood floor (nothing fancy, the kind that clicks together like a puzzle). The material layout of the room will then be like this... Floor - Wood Walls/Ceiling - 2 layers of 5/8" sheet rock. No windows I have an interesting idea for the walls. I want to have the option to make the room sound really live. This past weekend i picked up a ton of cabinet doors that were made to the wrong dimensions by home depot. The doors are in perfect condition and are solid oak. Some of the doors are 2.5' X 5'. My plan is to make a system where i can hang these cabinet doors on my walls if I want the room to sound really bright and live. On the other side of the doors I would put acoustic foam so I have the option of making the room really dead if need be. Are there any potential problems with having so much wood in one room? Does it get too live? The area that used to be a closet will be completely covered in foam so I can have a "dead end" to my studio for guitar amps and vocals etc... Thanks for the input!

I know I am not going to capture a magic room tone with this space but I have experienced good results on certain instruments when recording in smaller rooms containing hard surfaces. Simple things like acoustic guitar sound so much better when capturing the early reflections etc... My main concern is to whether or not the room could become too live. Anything against using Oak as a reflective surface? I know its not exactly a tone wood...
