Klauz weapons are already dead in the water anyway because you can't multiweapon with them which is a very important mechanic for NGS. Also pretty sure that NGS weapons are just stronger too.
8 slot Klauz "god units" are also weaker than 4 slot NGS units in terms of pure power, although the minimum damage variance is higher on the 8s unit which probably pushes it ahead, but NGS units have FAR more defensive ability than Klauz units as well.
Furthermore, anything could change from the CBTs to release. They already changed how HP and PP affixes work when transferred over, they could change anything, so until there's actual concrete info about release, you really shouldn't be "prepping gear for NGS".
Preparing gear for NGS is going to lead to a lot of disappointment most likely, especially since that gear is locked until a higher level, in which case you'll probably find better stuff. You're much better off making PSO2 gear for PSO2.
