Not recommended. How will you know if (for example) the user change
his password later? AAAF will always reject it later even if the
password is actually correct.

That being said, you MIGHT be able to work around that by:
(1) forcing PAP
(2) logging user passwords for succesfull auth (see radiusd.conf)
(3) parse the log (a simple "awk" or something should work)
(4) insert manually to db
the "forcing PAP" part is necessary cause if the client uses MSCHAP
you won't be able to see the cleartext password.

As an alternative to (2) - (4), unlang supports arbitrary SELECT query
(something like %{sql:.. , see
http://freeradius.org/radiusd/man/unlang.html). But since you need to
do an INSERT (insert user password to db), you need to work around
that. See http://www.mail-archive.com/freeradius-users@lists.freeradius.org/msg51742.html
for example.
