Is it possible to install multiple WPG2 on wordpress??

first of all i apologize for my english. A big thank to everyone who will try to get at the and of my post trying to understand what i'm going to ask you.

Well, here comes my question:

I've been requested to install multiple gallery2s on the same website using wordpress.
The first gallery2 shows pictures taken from flickr, the second should show limited access galleries for some users only. I know i can create such "private" galleries using only one installation of gallery2, but i have to insert a link called "photos for you" in the website main menu.

I've succesfully installed the first gallery2 and i've installed WPG2 on wordpress also. It works fine.
All images have been succesfully imported from flickr.

Now. I can install a second gallery2 on the same server, but how can i insert this second one into wordpress?
I need to install something like a second WPG2 plugin "linking" the new "private" gallery2.
Mi idea is to change the plugin name so that wordpress treats them like 2 different plugins.

Is there a way to do that?

Please answer, even to tell "no way!".

Thanks
Matteo
