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
/dev/ad0s2e    257838    1624   235588     1%    /tmp

/dev/ad0s1g   7480506 2061124  4820942    30%    /stable/usr
/dev/ad0s1f    257998    2142   235218     1%    /stable/tmp
procfs              4       4        0   100%    /proc
$


If was booted off stable, the -CURRENT stuff would be on /current/...
