Map multiple Domains to blog pages

Hi,

just stumpled upon a problem. I got 1 blog and using it as cms. (No network, just 1 blog)

No I got like 5 pages. 2 of them are static and 3 of them should be the front page of the blog. It should depend on the domain which of those 3 pages is the front page.
The 2 static pages ar linked in the footer. They contain the legal and privacy stuff.

Example:

http://www.cool-page.com => Page 1 is frontpage
http://www.bad-page.com => Page 2 is frontpage
http://www.nerdpage.com => Page 3 is frontpage

I need this, as all those pages are landing pages. The all work like

http://www.cool-page.com/page-1
http://www.cool-page.com/page-2
http://www.cool-page.com/page-3

but I want to have different domains for this and no redirects.

Has anyone an idea how to solve this? Is there a way to have multisite with just different options-tables, but identical content tables?
