Landing Page to two "different" parts of website

Site URL: https://www.galsandghouls.com/

Hello!  I'm looking to possibly transition my company's website to have a landing page where a client can choose which side of the business they are looking for.  Clicking on either side will take to a different "homepage" - where the logos are different and the navigation may have some of the same pages but not all of them.  I've attached a general example of what I'm thinking.  Is something like this even possible?  Will it require an additional Domain or can I keep it within my current domain?  I'm not necessarily married to the current template/style if there is something else that would make this possible.  My current template is Moksha in 7.0.
