Membership - bypassing subscriptions and showing registration form on front page

Membership is a great plugin! Though I'm running into a few hang ups.

I have two levels - free subscribers and invite only private clients (also free).

I would like to have a registration form on the front page for free subscribers by passing choosing the subscription level (as there is only one).

I tried using the [subscriptionform] shortcode but that just offers me an explanation of the subscription levels (not needed) and takes the user to an unformatted page with yet another button to push before getting to the registration form. I'd like to eliminate all off this and just have the registration form on the front page. One stop with no other pages to get through.

Is this possible?
