Can I swap stereos between a '98 Honda Accord and an '01 Ford Focus?

I have a stereo for a 1998 Honda accord that I no longer use. Would it fit in a 2001 ford focus that has no stereo? A fit guide says the Honda takes a Corporate Panel size, and the Ford takes a Corporate Double Din. Both have an 8" depth. Is the stereo completely incompatible; or will the issue be merely cosmetic?

It could be installed and made to work but a new fascia should be created for it.
