I've done it successfully more than 10 times, but:
- It isn't officially supported
- I did it on virtual machines which by their nature had fewer
packages installed and are much simpler than the typical desktop
or "server that does everything" in a small office.
It is not for the faint of heart and on any moderately complex
install it is faster and certainly easier to just reinstall.
Basic process:

Do not do this if you aren't willing to possibly render your system
unbootable requiring a lengthy repair session before you get
frustrated and just reinstall anyway.
So far in this thread people have pointed out that upstream software
vendors are increasingly moving away from 32-bit x86 for various
reasons. What hasn't been mentioned yet is that one of the upstream
projects where 32-bit support is sub-optimal and getting worse is
the Linux kernel itself.
Basically there are already fewer upstream kernel developers that
care about and understand 32-bit x86, and bug and even security
fixes specific to 32-bit x86 lag behind those for amd64. KPTI fixes
to address Meltdown and Spectre took an extra 6 months to reach
32-bit x86.

If your hardware supports it then you are best off planning to move
to it sooner rather than later. X86_32 is already in the critical
care ward.
Cheers,
Andy
