"Traditional hubcaps" are placed on heavy, black-painted steel rims that are generally considered "ugly" but steel rims would get their paint scratched over time as well. Aluminum wheels aren't going to fare any better.
If you always drive with the aero covers on, you won't see the scratches. If you take the aero covers off at delivery and never put them back on, you probably won't have any scratches.
Powdercoating the rims might provide a tough-enough finish to avoid the scratches, maybe. But if I were going to go to any expense, I'd just replace the Aeros with Titan7s ($$) or TSportlines (which look similar but a bit more budget-friendly, though not forged) and call it a day.
