Can I take the front lens out of a pocket AF-camera and replace only its front lens by a telescope, keeping the AF? (1 Viewer)

Hello, I made some adapters to digiscope my phone and Nikon Coolpix behind my Kowa or Celestron. After some precision-tweeking they work fine, the phonecam has the best autofocus for this purpose. Compared to using the bare frontlens of my Celestron as a good but MF telelens on my Olympus DSLR, I love the autofocus (and connectivity) that you get with the phone behind the telescope. Makes my digiscope much more agile. But: there is lots of loss of sharpness, contrast and corners (vignetting) due to too many glasses.

In theory it should be possible to get much better results, when removing the telescope eyepiece AND the front lens of the Coolpix out of the sequence, still keeping the autofocus (and the zoom-function?) working.

Anyone heard this is done? Maybe also possible with a spare smartphone? Of course I would need to make precise plastic adapters, I think I could, eventually.

But befor I start sawing my Coolpix or even my Galaxy S8: Anyone heard of previous attempts? Any chance it might work? Thanks!
