You could just make almost any Adapter with something like a Lenscap + C-Mount Extention Ring, some Grinding and Hot Glue.
At least if you have some Tools and are somewhat handy.
I dont have a Chronos yet, but if i had one, i would have found a Way to mount my Lenses on there, even if i just had to use Tape and Cardboard.
.
But proper Adapters really make Live easier, if you can get them anywhere.
Especialy if you have to rely on them.
I really hope that there will be Adapters some Time soon for MFT --> CS and N1 --> CS, also maybe Sony E --> CS.
Also hoping for some Company to start building Speedboosters for Nikon1-Mount and C or CS mounts and selling those.
.
Interchangeable Mounts for the Chronos would be also a great Idea.

Any details on the prototype CS to MFT?  Something we can 3d print or laser cut to play with and test?
The biggest thing stopping me playing with any of the better lenses is that I'd have to buy them and they are not worth it for the quality improvement alone if it means a dramatic rise in F-stop.
.
I just made a 3D-Printable Adapter to mount anything with MFT-Mount on the Chronos.
Downloadable STL-3D File Uploaded in this Post.
Realy quick & Dirty, if anyone can do it better, please do so.
Since i do not have:
-A Chronos yet
-MFT-Lenses
-A 3D-Printer,
I can not gurantee for anything and not even able to test that 3D-Model i just made.
So please Someone here try, if it works or if that 3D-Adapter needs Modifications, and post here, so other people Know.
I am not even sure, if the Lens Mount is Rotated Properly.
Should fit the Front of the Chronos with those four M4-Holes to be Mounted with four Screws.
Keep an eye on your Lenses, when you try to mount it, because i do not know if there will be enough clearance to fit your lens without hiting or Scratching your camera or Lens.
Also not sure about how strong that Adapter is, so be carefull and do everything on your own risk.
.
For the Design of the 3D-Model i simply assumed, that the Flange focal distance of the CS-Mount of the Chronos would be the same as its Bodys Front Surface.
I added one Picture, showing that this seems not to be like this, and the CS-Mount stands off of the Front Surface somewhat.
Because that Distance seems to be very small, it should not be that big of a Problem. you will Reach infinity Focus, but you cant focus as close as usual (will be more apparent with wider Lenses).
If someone can provide me the exact dimension of that Distance, the CS-Mount is elevated above the Front Surface, i can change it in the 3D-File.
.
Because of the Dimensions of that Adapter it would maybe even Possible, to Leave it on, while mounting C- or CS-Mount Lenses.
