Possible to duplicate hacked forum for use on other site(s)

[FlyBoy73]

I had this done for me a while back with a custom job for one of my community sites. The designer/coder created site #1 and then copied it for the most part (hacks, most of the graphics, etc) to site #2, which was a different topic. He only charged me a very small amount because he said that he didn't have to re-do most all of the hack work. Basically, just dupe/copy it to the new site, adjust a few settings, etc.

The two sites I am referring to are:

#1 www.PWCRacer.com/forums

and the duped version

#2 www.ADDForums.com/forums

As you can see, they are very similar, though there are some differences.

I am now wanting to completely upgrade #2 to vb3 and add a lot of features. Another site that I have is heavily modified and has a lot of custom coding in it. It is runs vb3.0.1. Is it possible to dupe a large part of this site and then make some small changes?

Thanks..
