Attach and Display NON-AUTHOR Username?

So I have a system set up where one set of people will write and submit posts as pending, and another, different set of people will get to choose which posts actually get published. The “choosers” will not be hitting the “publish” button themselves, but emailing me their choices.

I’m using the Members plugin, and have the “chooser” group set to have ONLY “read” and “read_pending_posts” capabilities. They can see the pending posts on a special private page I have set up just for them. They have no posting capabilities, but will be registered users first at the level of this custom role I have set up, and then will be demoted to subscribers.

I’d like to display the username/website link of the person who CHOSE the post for publishing, but NOT the actual author. I hope that makes sense.

I’ve looked at a couple of co-author plugins that would allow me to attach the chooser as a co-author and display names that way, but that would display the original post author as well, which I DO NOT want. I also considered using a custom field scenario, but I’m using the Custom Field Template plugin for the ease of those actually submitting the posts…adding new “chosen by” and “chooser’s link” fields would just confuse them, and I have the plugin hiding the normal custom field module for the same reason, so I can’t use custom fields.

The closest I’ve come is to put the chooser’s name in the content area (it’s empty otherwise, everything submitted is custom fields only and Contribs don’t even see the content area on the add/edit post page per Adminimize) and call the content into the line I need the chooser’s name displayed, but stylistically, that didn’t work. I’m going to go dig around in my CSS to see if I can strip any style from the content itself, but anyone have any other ideas on how I might accomplish this?
