Your asking a question that even a year ago may have generated a different answer. My suggestion, be careful on what you decide to do in your home in this current market. Your location, what the market is like in your particular area, what is the price range that the homes are currently selling for. Your doing a wise thing in asking experts to give you advice. My experience tells me that it is hard to recoup an investment like this in our current market. Maybe scale it down a bit.
