Subscriptions and Temporary Levels?

I have a site which offers 3 levels of subscription plans for access to different features, these being Basic, Gold, and Platinum. Fees are to be charged on a monthly basis. I have a use case to be able to do a one-day "uplift" to a higher level for a fee. after 24 hours, the subscriber would return to their previous subscription level. Is this possible?

In addition, I'd like to use member roles to indicate the subscription levels for access to content. Can member levels be automatically assigned a registration time based upon the subscriber's selected level?

Thanks,

Dave
