Kodachrome if developed in a B&W developer will produce a B&W negative (I've done it but it was decades ago and only as an experiment). That said, one also has to get rid of the anti-halation stuff and yellow filter which normally blocks blue light from hitting the orthochromatic (green/yellow) layer and the red layer below it (they're also blue sensitive). That's messy too.
Really I wouldn't bother (but when done properly it did turn out some pretty decent B&W prints.

- hilbert42 4y agoWhilst not common, that problem is far from being unheard of. I've had similar experiences albeit only two instances where 'good' film was developed by commercial operators who put the films through the wrong processes. With much Photoshopping I actually got usable photos but they certainly weren't pretty. That's different to experimenting. Years ago I worked for a television station that had a huge Eastmancolor processing lab attracted (we processed millions of feet of movie stock per month). Running various 'non-standard' test strips though the baths proved very interesting. We produced many strange effects (it was an excellent way of getting to understand how color emulsions work).
