Well, there IS that one line of dialogue at the end:
"Federation ship Enterprise: surrender and prepare to be boarded."
Spoken by a Klingon on one of the two remaining ships. I always thought it would be cool if just the VOICE would have been Worf
Agreed, just put the right amount of static on the voice so it doesn't *immediately* sound like Worf. Make the audience think about it for a few seconds first.
Side note: This is why I still, to this day, think that the one line in ST:FC "Acknowledged" (when the fleet admiral hails the Defiant
and the Bozeman
during the battle scene) is actually spoken by Worf rather than Captain Bateson.
