Hello raj_10021,
Yes this is possible. You need to look into a Wordpress plugin called WP theme changer, or something similar. After you have uploaded your theme files in the themes subdirectory, and have tested each one to be sure it will work properly with your blog, you can enable the WP plugin. Usually you will see a dropdown box in your sidebar that visitors can use to select the theme they want. But what you can do instead, is simply pass the name of your theme as a variable in your URL to the next page.

I don't think there is an automated way to do this, so you will need to look for references to the next page, and manually add the name of your theme as a variable in the URL. These manual changes are to the code inside Wordpress. Let me know if you run into any problems. This is easy enough to do in PHP, but you'll need the WP plugin to serve as your foundation. Good luck.
