I don't know how many different ways I can say "this idea would never work".
Well, trying something incredibly simple to understand, you could always say
"this idea would never work, and the reason for that is.. <and insert
your explanation of why it would fail to work here>
".
Otherwise, it's looking like you don't actually know why it wouldn't work, and are instead just stalling in the hopes that someone else will come along and pull you out of that pit you've dug yourself into.
But, that's just my casual observer opinion.
