Change Theme for Specific Page

I am very familiar with creating Custom Page templates and using an entirely different stylesheet by using conditionals in the header however, I need a little more than changing the stylesheet and layout structure.

For certain pages, I want to actually change the theme being used. So I’m thinking there will be a conditional ( if(is_page(‘members’)){ ) that will activate a set theme if true. For the theme activated conditionally, I want to be able to apply theme option settings Only for this theme – making sure to not disturb my options settings for the global theme.

Any thoughts on how I can achieve this?

Thanks
