Would this function be possible to mod?

Hi,

I'm currently working on a forum project and have concluded that VBulletin is the most robust. However, a feature we want to implement hasn't been done to the best of my knowledge.
Before I go ahead and purchase a license, I'd like to know if such a modification is even plausible and whether or not it conforms to VB's licensing agreement

On the front page of the forum there will be general forum categories, with topics relevant to anyone no matter their location.
Below these forums will be a box/window with a list of regions (e.g. NY, California, Florida, etc.). When someone selects a region, that region window will now be replaced with a forum for that region (regional news, regional events, etc.) and the universal topics above, will be retained.

When selecting this forum, would the logo be able to change for one customized for selecting region?

If someone could advise me on this, or even point in the direction of a VBulletin developer (I hope that isn't breaking forum rules), I would much appreciate it.

I'm of course hoping this is all possible, as VBulletin is really looking quite good to me.

Thanks in advance.
