Think about it for a minute.
For conversion you would need to decrypt the blowfish encoded
passwords and then to encrypt them using MD5 or DES encoding (piece of cake)

The whole point about these cyphers is that decryption is very 
hard. 

So forget that route.

- assign new passwords to each user and notify them by snail mail
  or another trusted channel

or

- implement blowfish encryption for FreeBSD passwords
