Sub Domains.Domains Transposed?

or will they search okay in reverse order?

I think I didn't do a very good job with the title of this question.

I have a site concept I want to develop using sub domains. The primary keyword targeted domain name is available, but I wonder how it will search when the subdomain keyword is added.

Example. paper.com is available. I want to create subdomains like paper.airplanes.com, paper.hats.com etc rather than airplanes.paper.com and hats.paper.com

Is there a way for a server to do be configured to reverse the standard order of subdomain.domain.com?

Or will the juxtaposed keywords (airplane.paper) search just as well as (paper.airplanes) if someone searches "paper airplanes"?
