Resizing pagination per_page on existing results

Is there an easy way to resize a pagination result? Effectively, I want to have a dropdown on a results page that allows the user to resize the number of results per page. Currently, I have something like:

      @search_results_pages, @search_results = paginate(:products,                                    :conditions => ["category_id = ?", params[:category_id]],                                    :per_page => 10)

Is there a way I can augment the per_page on existing results if I say wanted to change the 10 per page to 25 per page?

Thanks,

Scott
