Form / Newsletter elements to Instant Landing Page

The v6 landing page took a long time to display and had a high direct return rate, so we are rebuilding the page with Instant Landing Page, which should improve speed the most.

We want people who access the LP to sign up for our newsletter, but ILP does not provide a form/newsletter element.

I know that the other candidate, Gempages v7 LP, creates a form/newsletter, but I would prefer to use ILP if possible because ILP is by far the fastest way to get the page to display.
