Garth raises a valid point. The Ph-G is a little bit more than 4 Phaser-3s duct-taped together.
How about this one:
Duplicate the Phaser-3 stats...
Accurate +1, Kill Zone 2, Precise and then add "Multi-hit 4"
Then you add a line to the rules stating that if fired in defense, the 4 hits (or pulses) can be targetted on several seeking weapons as desired. This would enable you to target one, two, or more seekers; although the fire would have to be declared prior to the first die roll.
This would still leave open the possibilty to add escorts / aegis at a later time.
