Helix system is really good, and that's why I based mine off theirs. I just thought of improving things a little bit.
That's awesome... Love the ingenuity.

I still think that >50% of the flow will come from the secondary filter and <50% from the stock airbox... but you're absolutely right in that we'll need testing to verify... maybe I'll be surprised!
