When black & white displays where discussed w.r.t. gamegrid.el, it was
pointed out that there may indeed still be a few people who use such
displays.
Besides that, as things stand currently, Emacs may be compiled without
support for XPM images. The PBMs are a fall-back then.

I don't know for sure, but I really doubt that. The XPM in
lisp/toolbar/ do not contain any information for mono displays, the
PBMs OTOH are obviously cleaned up carefully.

You could convert the XPMs from the command line with the Netpbm tools
<URL: http://netpbm.sourceforge.net/>. I have not looked at your
icons, but converting colour images to black&white has a big chance to
result into ugly images that are hard to recognize. So I guess they
would need some manual clean-up.
