Permanently rename fields with the field alias

[MarkVolz]

I would appreciate if there was a geoprocessing tool that will permanently rename the fields in a feature class with the field alias.

It would be pretty straight-forward to do this through Python with Field Mapping, but the issue would be Field Aliases don't have the same restrictions as field names do such as names with spaces, contain invalid charaters not to mention you can have multiple fields with the same alias name.

This can be accomplished using the "Use field alias as name" parameter in Export Features.
