Well there as many people wanting a larger family room as there are wanting a garage. I think you would just be substituting one client desire with another. 2600 sq ft is a nice size so I would vote for keeping the garage
Since you were wise enough to invest in Southlake your potential buyers may be purchasing for the appreciation value if they make major changes to your home after they buy it.
I actually won't show a home with no garage to my clients even if they ask to see one. I tell them not to think about the home they are buying only through their own eyes, but through the eyes of the buyers who will be buying from them.
If you want the best internet marketer in the area give me a call.
There are, always exceptions to every rule and your neighborhood and market are unique.
The 2013 typical Southlake, TX Homebuyer, is expecting to see a full size attached Garage.

Should you decide to Sell your Home, Consider consulting with your local market experts on Garage Conversions and how it may or may not affect your ability to Market your Home strategically.
I've attached a good article on Pros, Cons and Logistics of Garage Conversions.
Good Luck, Sir.
