Certainly, but it isn't clear if this will add to the security. I'll
also point out that if you pick particular lengths you *might* end up
causing parts of the keying material to be applied in non-optimal ways
-- I haven't studied it enough yet.
Certainly you could do something naive like doubling the key length
from ten bytes to twenty bytes, but again, one wonders if, as with
DES, the key length was picked because it was known that security was
no better than that many bits...
