Spotting scope eyepiece adapters

[NY700]

I currently have a Celeste on Regal M2 spotter. Honestly I think image quality on this thing punches well above its weight class. Only drawback is there is not reticle eyepiece availability.
There are adapters for Swaro and Kowa and others to convert those scope to more tradition 1.25” eyepieces that are used for astronomy.
The Celestron uses 1.25” eyepieces. Does anyone know of an adapter that goes in reverse that might mount a vortex or Nikon MRAD eyepiece to 1.25” scope?

The adapter is less of a problem than the eyepiece. in order for the eyepiece to have a correct scale, the focal lengths need to match. In addition, if the lens is not positioned correctly you may not be able to get focus.
