Hi Robert,
>>>>Are you on the AIF development team by any chance?
I'm not working for SAP if this was your question but I'm part of the IFG for Integration group and an SAP Mentor so we can always try to influence SAP with good ideas
>>>For PI proxy interfaces, I see AIF has the ability to generate structures automatically based on the PI development
I think the word generate is a bit misused here - AIF only populates AIF structures from proxy structures, it does not generate anything new
>>>>Since I do this, AIF Sees this as an OUTBOUND interface, not an inbound interface, and generates the structures as a destination structure instead of a source structure.
that is correct - that's why SAP uses SAP and RAW structures and not source target as SAP and RAW structures can be different depending on the interface type (inbound, outbound). So it's exactly as described in the description of the SAP and RAW structures right ? So why would you want to change that ? 
Thank you for the update, hope I didn't confuse even more
Best Regards,
Michal Krawczyk
