A new idea(kind of)

When I was bored I started creating a script like a CMS but is limited in controlling one template and is made for the specific template.
Like a template with control panel.
Unlike a CMS it has one template and an admin panel to control post everything about it.
Do you think this is a good idea?
Here is what I have created so far:

http://imagenic.net/images/rh52znorjiw1e07mruus.png - Admin Blog
http://imagenic.net/images/74obrpz0ojvcoi7y458o.png - Admin Pages

This is just an example of it should I continue to make them?

 

This is good..... Just finalize it and then improve design a little and then see what you can do with this!

 

Thanks,
Any idea of what I should sell it for ?

 

My advice is to leave it open source and then sell its themes

 

Ahh but ye are wrong.
It's a single theme with a control panel
You can't install more themes on it

 

Wordpress killer, for sure!

 

And may I ask how?

 

Thats fine.... But what this CMS reffers to? I mean it looks like blog but what more??

 

It's more of a control panel.
It controls the theme to add pages and blog posts.
