I suspect weight isn’t too much an issue, since most reputable companies would account for it in designing their system.

The main thing I’d be concerned about would be debris across the impeller and what it does to the impeller. However, if it’s a system worth having, it’s worth making it a two stage, which solves the debris across the impeller problem. You seem to have solved that problem, so I would not be too concerned about the material the impeller is made from.
