Custom Author Bio by Multisite Installation

I realize I am probably the only person who may want this feature but I will explain why below.

WordPress finally injects the User account’s Biographical Info (description) into the “Author” page (at the theme level). I love that. I really do. Unfortunately, I’ve been using an Author Bio plugin that did this for me in the past and I didn’t realize until today that the plugin is no longer necessary.

No biggie, except that I want to have different bios based on my interests when I’m using a WordPress multisite installation. WITHOUT having to hack themes and plugins. ??

So, on one domain I want a “main site” where I give Professional Bio ALPHA in my “Author” page. On a sub-domain of that site I want to give Special Interest Bio BETA in my “Author” page.

I also want to use two completely different themes to accomplish this.

If I have deciphered the code properly, the “author.php” files are integrated with the themes, not with the core WordPress files. So if I just absolutely had to have this capability today I would have to boldly hack each theme I’m using and then hardcode my separate bios.

Alternatively I can set up different users and just post under them — but I’m in the position of having hundreds of posts and no easy way to change the user attribution.

So what would work for me (assuming the entire WordPress universe wanted to stop what it was doing and fix my personal problem) would be to have the “author.php” page in the core WordPress section, and then to have some sort of delimiting option where I could write alternate bios for each defined site.

I have no idea of how/why the author stuff is set up the way it is. I’m sure there is a lot of history behind it. But I figured it wouldn’t hurt to leave the suggestion here.
