It's somewhat possible, but not with Marketo alone. ShareMaker, one of my recent experiments, can "burn" static pages based on a personalized page, and the static pages are immune to the problems of (1) associating clicks with the original lead and (2) personalizing the page with the original lead's info.
However, it must be admitted that as long as the dynamic page URL is in-the-wild, you run the risk of somebody sharing that page instead of the one you want them to share. With ShareMaker, you sidestep that temptation because you only give people the ShareMaker link to post to social media, so SM always generates a "neutralized" page. In your case, if you're sending people a tokenized dynamic URL to an LP, even if the LP itself has a sharing-safe URL in the page content you can't truly stop people from sending around the URL that's open in their browser or that they see in their email. (On the browser side, you can try to inhibit direct sharing by stripping off the query string after the lead is associated, so the URL in the location bar doesn't have the ?mkt_tok in it.)
a good jumpstart is to send me an email from your Marketo instance. Then I'll send you back a SM URL so you can see how it burns static LPs from emails. .png)
