You can try using one freebsd-zfs partition, one pool and just change
bootfs zpool property:
# zpool create rpool ad10p3
# zfs create rpool/ROOT/amd64
# zfs create rpool/ROOT/x86
# zpool set bootfs=rpool/amd64 rpool
echo 'vfs.root.mountfrom="zfs:rpool/amd64"' >> /ROOT/amd64/boot/loader.conf
echo 'vfs.root.mountfrom="zfs:rpool/x86"' >> /ROOT/x86/boot/loader.conf
and then change bootfs on the fly:
amd64# zpool set bootfs=rpool/x86 rpool
amd64# reboot
x86# zpool set bootfs=rpool/amd64 rpool
x86# reboot

Everything should be made as simple as possible, but not simpler.
