You can always "up-convert" your colorspace before cropping, and
"down-convert" afterwards:
$ ffmpeg [...] -vf format=yuv444p,crop=h=1:...,format=yuv420p [...]
or something like this.

(I don't know if it's technically impossible to crop a yuv420p to an
uneven number of lines, or just not desired. The color information for
that one single line does exist...)
