-Make bandages, healing salves, potions, etc stackable? -Remove the "NPCs wont talk to you because of aptitude" checks?
A loophole/bug rather than a hack, but even in the latest version of the UAP, tech shopkeepers will talk and trade with a player with a high MA if he casts Shrink on himself before starting the conversation. The spell goes around the check and makes shopkeepers ignore aptitude, so it works just as well for magick shopkeepers and players with a high TA. If a highly tech player would happen to know that spell, that is.
I figured that much. My point was to give you a solution which you could have here and now, though, seeing as you might not have much of an alternative here. Perfectly possible to do, though you would probably have to modify game files by yourself. Don't recall anyone creating and sharing such a hack. Also, no created mod for stocking bandages/salves/etc. If it's possible, it's definitely a more complex mission than the first one.
