Dear Lorenzo,
Color editing in CMYK is usually for slight color tuning. Not for color matching. If your customer knows everything about ink coverage, gray balance, black generation, I would say they "could" make small CMYK corrections. If what they want is to "match" untagged CMYK files.... good luck! They will have to tweak (with trial and error) for ink coverage, grey balance, TVI, etc. Editing "untagged" source CMYK files, is like trying to match "unknown" colors!
As for building ICC profiles, I suggest you to take a look at our ICC profiler called PerfX Color management™ (Pro, Repro, Studio). We’ve just put an interactive demo on our web site. If you have questions, feel free to ask!
regards,

_____________ I know that there's no "CMYK working space" and dealing with CMYK to CMYK conversions is asking for trouble. The question is which CMYK profile should the print guys use when editing the files? The printer profile? It seems very odd to me... They receive untagged CMYK files from their customer (actually, they ASK for untagged CMYK files), so the customer does the separations.
They run large ink-jet printers (solvent based) driven by Scanvec Amiable's Photoprint. Any recommendation for building profiles for these printers ? (which target, number of patches, ink limit, CGR settings, etc).
Best regards, Lorenzo _____________
