Does one also crimp the inner, for it seems far
too tiny to survive such physical action?

Also, with general purpose crimping tools, when
fully open, is there sufficient room for the
assembled BNC plug to pass back through the opening?

(Visions of a double-ended BNC lead with the crimping
tool forever doomed to dangle from the middle :-) )
