I don't think it will change balance.
Satellites are a poor platform for direct fire weapons. Even with sensors 3 and RT 3 (!!) my satellites have a tough time hitting AI' frigates and destroyers. Missiles are better but a normal sized AI fleet (30+ ships and fighters) can easily kill a large stack with minor loses.
Besides, 100 stack is a major investment and should be give a trouble. Otherwise, why bother
