This is VERY cool. I had no idea you could do this. Thanks for sharing! Maybe eventually there will be a way in gmail to create a toodledo task automatically.
I doubt Google will ever make a button to turn a gMail conversation into a Toodledo task in the way you can currently turn it into a Google Task, but there are some fairly easy ways to do it yourself-
If you're using Firefox, you can use the official Toodledo plugin http://www.toodledo.com/widget/firefox_plugin.php to right click on any page to add that page to a Toodledo task, which in the case of an opened gMail message, will automatically put the page URL to link it into the notes of a new task that you can immediately start filling out then and there.
If you don't wanna go that route or are using another browser, you can add Toodledo as a gadget to gMail (explained here http://www.toodledo.com/widget/google_gadget.php). That'll make it so there's a small Toodledo client running in your gMail window, and you can easily just paste the gMail conversation URL into the notes of a new or existing task there.
