I don't think that you can actually create any features with anything other than Pro/Toolkit, so I think you're out of luck.
As an aside to your larger problem, we get our aerospace parts with both a part local csys, and a reference 'global' placement csys relative to the entire aircraft datums (front of nose 0.0.0). When assembling, all components are placed by this global csys only, ignoring any local mates, inserts, etc... Fasteners, for us, are not usually modeled, except for rod-ends, etc, and these are also placed by the 'global' csys to aircraft center.
This makes replacing any component relatively simple, and then testing placement by looking for any interferences between neighboring 'mating' parts. This also makes 'concurrent' engineering relatively straightforward, due to the 'spaceclaim' by any neighboring components will not change with regen, and you will not get circular references, etc...
Also, any and all parts can be replaced by 'simp reps' very easily for other studies.
Just my $.02

thanks for your reply! What you describe is indeed similar to what I have in mind. It makes me curious, though: if you have more than 1 item of a certain model, do you add extra coordinate systems to the model??
