2 themes same content?

Is it possible to have 2 different themes/template look on the same modx install but using the same web content? I run a gaming website and there’s 2 games that the guys play. I wanted to create theme based templates but would like to have the same content on them. I want to have it all under one modx install and if i update the content then it updates it for both sites. I’m using friendly urls so I’ve had to name the home page for example home.html and the other home1.html otherwise it won’t work obviously. Is there really no simple way round doing this?

There’s a template changer plugin that I think you could modify to suit your purposes.
