Was I wrong on Karyograms?

I got a tip a few days ago, that uneven cross over could create new chromosome which could co-exist with old, eventually as a new pair.

I asked for a diagram, got none, and did one myself, for 8 possibilities:

Possibilities I and V are fairly normal crossover. IV and VIII look interesting. II, III, VI, and VII all look as if we could get to a point where a double centromered chromosome breaks - which would lead to at least one of the resulting chromosomes having two telomeres with no centremere between.
