A snippet can see any of the variables available during the request, so you could easily just do this in a snippet called EchoTheme to echo out the value you passed in the request:
Yeah I think the template switcher may be overkill. I am not sure how I could use a snippet through.. How would the snippet know the context in which a page was run?
<?php $output = isset($_GET['theme']) && !empty($_GET['theme'] ? $_GET['theme'] : 'default'; return $output; ?>
No, a weblink is a redirect to another page entirely.
I just saw that a weblink will accept TVs. Is there any possibility that a weblink to a document would override the TV of the documnet with the TV in the weblink?! Probably not.
@DOCUMENT only pulls in the content field from the specified document. Any tv values that are parsed in that pulled content would applied from the document that was actually requested.
How about this - lets say I have a document that pulls in a @DOCUMENT - if they both have the same TV set, which one wins?

That snippet would echo the theme name anywhere you put the snippet, i.e. [!EchoTheme!]
[PLEASE NOTE that this code is bad, in that you would want to do more to validate the value of $_GET[’theme’] before echo’ing back into your page content; malicious people love when you do not validate user input like that...]
