AS long as they are all UFS1, it'll be fine.
I do this with my /shared (and actually all of them) partition:
$ df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/ad0s2a 1030702 121770 826476 13% /
devfs 1 1 0 100% /dev

procfs 4 4 0 100% /proc
$
If was booted off stable, the -CURRENT stuff would be on /current/...
