Hi Shawn,
I might be wrong but I don't know any extension that would make this possible.
The Marketo tracking (munchkin) gives you the advantage to track individual people and not just "overall" information. So you can track, score and use information on individual users page views/clicks. But you can also use it on your website so I don't see a big advantage of Marketo landing pages except the easy creation. But you should add Munchkin Tracking to your website.
Best regards
Steffen
