What I'm driving at, can I run a ringer from Ring to Earth ground?

(I don't have enough pairs :-)

Well, that was how selective ringing party lines worked. but
modern CO's use tip to ring. You can not ground tip; it is NOT
grounded except during the ring cycle. And it's not at audio ground,
period.

Unbalance the pair and you'll not hear anything but 60Hz.
