you can pass whatever you want, but gallery will only interpret and process the $_REQUEST variables it has been programmed to use.
You'd have to add your own logic for whatever $_GET[ "rt_id"] is.

The easiest way would be to embed gallery into a page and have the page process your custom $_REQUEST variables or write a gallery module to handle them.
For instance in this example I use a variable for setting the theme dynamically:
http://www.flashyourweb.com/gallery2/embed_samples/gallery_embed_template.php?g2_itemId=24203&g2_theme=matrix
http://www.flashyourweb.com/gallery2/embed_samples/gallery_embed_template.php?g2_itemId=24203&g2_theme=clear
http://www.flashyourweb.com/gallery2/embed_samples/gallery_embed_template.php?g2_itemId=24203&g2_theme=carbon

I also use jQuery to append my extra variable ;)

You don't have to go quite that far.
You can use galleryUtilties::getFormVariables(...) to get the values; that means the data you get is already sanitised and safe. Obviously you have to write the code to use that data.
