hey guys

is there any way to point a domain name directly at a page when the site already has a domain pointing to it?

say i have site bluewidgets.com but i bought another domain with better keywords round-blue-widgets.com and i can't change the domain over because the bluewidgets.com domain is the main one used for email. My thoughts were if possible to put up an optimised page with a link to the main site, not a redirect like doorway pages, and have the new domain point directly to that page on the same account (this is for a client without a reseller account )
