I’ve finally done the mod myself as well:
I’ve made some modifications to the adapter that was mentioned earlier in this thread so you can adjust the height with a nut:
this makes the installation a little bit more convenient and easier to do (what you see printing in the video is actually the wrench I needed to finetune the adjustment as the clearance is rather small 
I’ve done some prints already and that works very smooth. I hope to see the biggest advantages when using the cnc function (which I will try later this week). Especially curious how it will hold up with dust flying around. The rails are just lying the base plate. Using some painters tape to make the slide around less. This seems to work pretty well actually.
I’ll make sure to publish the stl files and a description on the mod later this week
