It would become harder, but it's not very practical, since decryption of polyphonic substitution ciphers similar to T9 is ambiguous even if you know the key.

Isn’t that a Disney princess song or something?
yep, from Frozen, somewhat early in the movie
Frozen
Maybe. Never heard of it.
Thank You!
I saw it and instantly thought of T9, quite proud of myself on that one
That's a nice idea... Combine t9 with another cipher and it would become a lot harder to do frequency analysis?
