Really? I have been doing it for years.
It's an extra six pounds (actually, five, since the aluminum plate weighs something). So you would simply need to decide whether taking an additional five pounds of baggage with you is worth not having to duplicate the backplate, webbing and whatever you have attached to it, and not having to wear a weight belt when you are there.
I think you will find the weight difference between your aluminum plate and stainless plate is about 3 lbs.
Aluminum plates don't levitate entire dive bags and cause them to float over to the plane.

When compared to the typical "full featured" BC many BP&W's are lighter even when a SS plate is used.
