This is sort of a continuation of a rules question i had on nanocytes using weapon accessories.
This shouldn't let you create hybrid items so if you wanted a silencer you would have to buy it and keep it in you inventory.
Modded Weapons - Nanocyte Knack:
You can Select Weapon Accessories as minor forms. When you create a weapon with a gear array, you may also create a number of weapon accessories equal to half your constitution modifier to be attached or integrated into the weapon. Alternatively you can attach weapon accessories from your inventory when you form a weapon.

Weapon accessories that attach another item can grab an item from your inventory and load them. If you have the item as a major/minor form it could instead create the item, but it will count toward your limit of weapon accessories.
