So you don't really think that a cipher can be made from a
genetic algorithm, then (note that I'm not saying that the OP's
cipher is good, I'm just asking a question)?

GA's generally lead to results which are next to impossible to analyse
for weakness. Not to mention you need a success measurment. The
question you ask a GA is "How successful was this combination?" For you
to ask that questions 2^30 times or more, you need a simple way to
answer that.

Find me way to score a possible block cipher (or *any* crypto primitive)
and I'll think about this futher. I haven't found any way.
