The KSC2 is an asset in the game and has always been considered an Easter egg.
In career mode the buildings can be upgraded. An alternative could be to purchase KSC2 and have facility upgrades but at lower cost. The launchpad and VAB have increased limits and a minor upgrade to tracking. The cost of purchase should be about 2/3 the total cost of upgrading the VAB and Launchpad.
The latitude will make launches cost more delta-v because launching due East will result in an inclined orbit. The launch tower is friendly and loves to kiss your rockets goodbye.
A method for creating fuel. Perhaps a faulty fuel refinery that needs equipment. A Drill-O-Matic assembly to be acquired (part is not in the Advanced Science Tech and is only intended for this site) and with resources in this area are always set to be high. The power and fuel storage would also need to be implemented to bring it back online and the player could attach these parts to the refinery using docking ports, A method for pumping fuel without upgrading the R&D for fuel transfer. Fueling the vessel via docking ports on the launch pad, runway or tower.
The landing strip could also be added and a pad area for vessel assembly and erecting would add further options to the site for a price.
Also a barn in front of those mountains would make an awesome picture.
