I find your prose incomprehensible - I can't be certain even what
problem you are trying to solve, never mind express an opinion on your
proposed solution. Could you please restate your question in a more
comprehensible fashion? Use shorter/less complicated sentences, less
nesting of subclauses, fewer buzzwords?
