Not on OpenBSD.  Solaris can handle 32-bit on 64-bit for ELF.

Static binaries should work.  Making dynamically linked ones work would
take more effort.  You'd have to recompile either a.out or ELF to use a
ld.so from a special location.  Or add kernel code to chroot, ala
compat_linux, and keep /emul/openbsd-aout around.  NetBSD has some code
for this.
