Is it possible to change templates using different conditions

Here’s what i’d like to do.

Main Page - On the main page I use a ditto call to call some of my recent news. I use fancybox to pop up an IFRAME to call the news using a blank template.

Articles Page - I also have an articles page linking all news and archives. I’d like to be able to click on the news articles using a different template.

Is there an easy way of changing the template if different conditions are met? or using $_GET variables?


Thanks,

Nick.

As TVs are depended to Templates, changing Templates by request does not seems nice or may be impossible.
I suggest to create a resource to only display iframe data. Put an Ditto in it and use Ditto request extender to specify resource ID by GET And link to news something like below:

Beware about accessing users to restricted resources by ditto parameters...
