GZG DS2: Noah's ADS Expansions

Hi, Noah! Here's my ADS variant while I read yours:

Other Weapons for Area Defense Systems
    To use another direct fire weapon system (other than RFAC/2, RFAC/3
and
RFAC/4 equivalents), mount your chosen twin weapons in a turret, and
work out the cost for the twin weapons. Multiply the cost by ten and that is
the price of the system in points. The range of the system is equal to long
range of the individual weapon systems. The ADS quality die is based on the
size of the weapon: size 1 to size 5 is D4 to D12 respectively. Draw damage
chits equal to size class of weapon. Even though two weapon systems are
fitted, only one set of damage chits are drawn. Damage validities as per
existing ADS damage validities, i.e. all chits count. To make this system
consistent with the current ADS, the DSII
basic ADS/ZAD should only have range of 24" (RFAC/2 max. range), and the
DSII enhanced ADS/ZAD should only have a range of 32" (HVC/3 max.
range). We
assume that HVC/3 is similar to RFAC/3.
