Now Photoshop supports conversion to multichannel ICC profiles, but does not support soft-proofing them - neither before not after the conversion. Need to implement soft proofing in Photoshop for multichannel files (with multichannel ICC profiles)

May I ask in which sector you work? Packaging by any chance?
Because I remember Mr.Cox mentioning some time ago that Photoshop would support ICC-profiles for more than 4 colors but so far I have never come across any being used professionally.

Ceramics. Unlike packaging, CMYK almost does not exist here, the majority of work is multichannel.

Photoshop does support multichannel profiles (under "advanced" in "convert to profile"), but in an awkward way: you can convert to MC profile, but can't convert from one, and most importantly can't soft-proof it.

It get's even more funny: one can see the soft proof when the MC profile is chosen and the "OK" button still not pressed. It disappears once the conversion is done. Meaning: the few lines of code that do it are already there, they just did not propagate any further...

Thanks.

And may I ask how many colors you usually print with?
(Just curious, we work mostly for print on paper, so CMYK it is usually.)
