removing domain mapping during checkout with marketpress/domain mapping plugins

Is it possibly to remove domain mapping during checkout as the default and instead have that as a premium feature?

The reason being that it is extra work setting up https for each domain.

I noticed that with shopi fy and square that make it so that during checkout instead of having the domain mapped, they revert to:

accountname.shopify.com/checkoutblahblahblah/ that way not having to do all the https work.

Is this possible already...?

Thanks for ur advise.e
