"Federation ship Enterprise, surrender and prepare to be boarded!"
I love this scene in Yesterday's Enterprise and have frequently considered the possibility of Worf delivering that line. Michael Dorn's voice would have been instantly recognizable to fans (that's always fun, to be a bit more in the know than dilettantes watching the show). We never see the Klingon that delivers that line, that would somehow make it more shocking. The best part though would have been the great multileveled nuance that casting would give the next line.
Picard: "That'll be the day!"
It almost feels like the line demanding the Enterprise's surrender was written for Worf.
The only conflict with canon that I can see would be if the attack on the Klingon Outpost Narendra III and the destruction of the Enterprise C happened after the Khitomer Massacre. In that case it would stretch incredulity (HA! Like that could ever in the Star Trek universe) that Worf could could become a Klingon ship captain. However, the Khitomer Massacre happened (correct me I'm wrong) on 11/10/2346 and the "C" was lost and presumed destroyed on 5/13/2344. Who knows? As long as the Battle of Naredra III happened before the Khitomer massacre, unless I'm missing something, it's anything goes. Maybe in the alternate timeline Mogh was the hero that destroyed the the Romulan Warbirds and saved Khitomer? (That's just a bit of hyperbole, not the question I'm asking)
The question is, is there anything I'm missing? Is there any reason (in-universe or otherwise) NOT to give that line to Worf?
I'm finding it difficult to understand why this question has been closed as being opinion based. I'm not asking if it's a good idea or if it makes sense. I'm simply asking if there is any reason within canon that Worf could not have attacked the Enterprise during the alternate timeline of Yesterday's Enterprise or if anybody has any inside knowledge of the thinking of the writers.

Re: The Time Travel Story “Old Enterprise” by Trent Ganino…what about this as a twist… we’re in this routine action story when in flies this old Enterprise through a time warp, however we choose, and immediately, things change without anyone on board realizing it. Picard is still in command..Riker, number one, Data in position, but Worf is gone (in fact a member of an enemy crew) and Tasha Yar is at security…
The above is a quote from The Making of Yesterday’s Enterprise by Eric Stillwell (emphasis mine)
The question of the possibility Worf's involvement in this episode as it relates to Khitomer is uninteresting and circular. As evidenced by the memo quoted above, at least at one point the possibility played in the minds of the series creators. As an answer to this question I would like to know why the creators chose not to use Worf in that way, or if there is a reason within canon that I am missing. Because the Khitomer Massacre happened (in our timeline) long after the events on Nerendra III, it's irrelevant to this conversation.
As written, this question is answerable. As a matter of fact, having found the memo quoted above, I might very well be able to answer this question myself eventually, if the question were reopened.
