Good idea. I checked the train and it is definitely doable if I stay more than one day. Not counting transit at the airport, my last time in Copenhague was in 1976 with long hairs and backpack.  It has probably changed, I guess

Great idea I'll join if possible.

Currently I'm inclined to wait until spring is upon us  But all is possible!

Nice work Jürgen.

It might be worth setting up a "how to" thread for others about to undertake this work - especially with colour negatives, which you are clearly well on top of.

I created the Picture Control preset in Nikon's Picture Control Utility app. Now, this can be done directly in NX Studio by changing the Picture Control settings accordingly and then exporting them to the camera. It is now also possible to invert the RGB channels individually and perform white balance, allowing for a basic conversion from colour negative to positive.
When this Picture Control setting is selected in the camera, the Live View image appears as a positive in NX Tether or other tethering apps, for example, making it easier to assess the image effect.
Because of this image control, continuous lighting is also more advantageous than flash lighting.
The bellows may be a little too long for the EL-Nikkor 50mm in reverse position, but this lens can also be used quite well in the normal position.
The vertical camera position has several advantages, including making it much easier to reproduce larger film formats. I use glassless film holders from the darkroom era whenever possible (where there is no glass surface, dust cannot settle).
Here is an example of a 6x12 colour negative digitised with the Z6 and 6048 pixels in width, below which is a 2000-pixel-wide section.

Same here in Australia.  At least they are consistent!
