Hello Lawrence:

> One could well enough compute the orbit of a charged particle in this spacetime.

If and only if the charged mass had the same sign as the charge on the test mass would the NS metric work. If th test had the opposite sign, it would fail because the metric must demonstrate attraction.

I am not sure where you got this idea. You can well enough compute the orbit of a charge with any value or sign in an RN metric.
