The 17 is operated by two Lolynes anyway. 5159 could be replaced, but not 5165 or 5166 -
5234 replaces 5151.
5235 replaces 5152.
5236 replaces 5153.
5237 replaces 5154.
5238 replaces 5155.
5239 replaces 5156.
5240 replaces 5157.
5241 replaces 5158.
5242 replaces 5159.
I'd imagine 5165 and 5166 would be replaced by cascaded Solars or B10BLE's.
