PS: Star Trek: A New Chekov?

Intro:

Since Anton Yelchin died by accident (he got hit by his car, suffered a blunt traumatic asphyxia), fans around the world mourn of his unexpected dead and wonder who would play his role in further parts of the new movie series.

The IMDb poll board users made up their mind about his successor in playing the new crew member Pavel (?) Chekov of the U.S.S. Enterprise. Since it is unclear if Chekov will be just replaced by another actor in the coming Untitled Star Trek Sequel, or will be completely left out, which seems to be no option for real fans, another option might be a solution. Chekov could be replaced by a family member – a brother, a cousin or even a sister. No matter if you would like the old Chekov simply be replaced by a new actor, or like the idea of overtaking his place by another family member of Chekov, the question is:

Which of these ideas would you agree the most? (please note: this ideas are highly speculative) Beam your thoughts here.

Rules:

Each user can pick one actor or actress for his/her/* idea of finding an acceptable replacement for Anton Yelchin's Chekov.

If you participate, please describe your idea. Is it a family member (e.g. Brother, sister, cousin, etc.)
