Just purchased a TeleVue 5mm Nagler Type 6!
THANK YOU @Oldfracguy!
I decided to slim down my already minimal eyepiece stable from 4 to 3 eyepieces, so I sold off my 7mm Nagler (original) and my 4.8mm Nagler "smoothie" and replaced them with the 5mm Nagler Type 6.
The 5mm Nagler Type 6 joins my 11mm Nagler Type 6 and my 24mm Panoptic for a 100% parfocal, field-ready high (94x), medium (44x), and low (20x) grab-and-go anywhere set-up with my TeleVue Ranger.
