(Kyzrati replied while i was still typing, call that timing!)
Considering how Constructs are being balanced, i don't really see these being added, at least not without some serious balancing changes, purely beneficial effects like that is something that it seems like is being avoided. That being said, i'm far from the best authority on this, so take that with a grain of salt. There would absolutely be a way to balance it, of course, but it would probably need a lot more than just mass, e.g. Power Amplifier increasing power generation, at the cost of a similar, if not higher increase in the Construct's heat generation, or something like the Weapon Cycler, reducing delay slightly, but also reducing accuracy, and adding to the power usage. But again, i'm not Kyzrati, so who am i to say?
I will say, though, i did have a related idea, of things like weapon shielding, power shielding, and propulsion shielding (which the Scrap Engine can use anyway) repairing EITHER the scrap engine or a relevant construct, depending which needs it more. Although again, i'm far from the best authority on this, i haven't even gotten to use the Scrap Engine for myself yet.
(also clearly it would be Targeting Computer for accuracy, Visual Processing Unit would be range, if anything)
