It's unclear to me how this would be different than standard panopticlick with >50% of the users using TBB.  But those not using TBB with had browser statistics like the rest of the web (for example, all of the tor2web traffic).

Hi Tor Community!

My name is Pierre and I'm a second year PhD student from France working
on browser fingerprinting. I'm really fortunate that my proposal for
this year Google Summer of Code has been been selected.

My goal for this summer is to set up a website similar to Panopticlick
or AmIUnique that will collect data to improve Tor fingerprinting
defenses. The collected data will be used to detect if there are
differences between browsers that could ultimately lead to a user's
identification. With that knowledge, developers will be able to patch
the Tor browser to prevent leak of identifiable information and
reinforce the anonymity of Tor users. I also plan to add details on
browser fingerprinting for users who are not familiar with the subject
so that they may learn about its mechanisms and the potential dangers
linked to it. I'll also try to implement a page where Tor users can see
how far they are from an "acceptable" fingerprint so that they may tweak
their browser in order to have a fingerprint that is shared by many more
users.

I'll officially start coding at the end of May but in the mean time,
I'll familiarize myself with the Django framework that I plan to use and
I'll lock down the exact set of features that I'll include in the very
first version of the project.
My primary mentor is Georg and my secondary mentors are Gunes and
Nicolas. I'll post bi-weekly reports to the tor-dev mailing list and to
my blog to inform everyone of my progress.

If you have any questions about the project, don't hesitate to ask me.
The name of the project has not been found yet so feel free to send me
any suggestions that you may have. You can reach me here or on IRC where
my handle is SuperOctopus.

Cheers!
Pierre
