As an OAI-PMH set, yes.... very easy

$oai->{sets} = [
   ......
   { id=>"creators", allow_null=>0, fields=>"creators_name"},
   ......
];


As a cgi call, or in code, is slightly more complicated.

My initial thought would be to create a script that goes through the 
dataset and builds a "list of hashes": where the author details are 
stored in a hash, and one of those key/value pairs is a list of 
eprintids for the records they are listed as authors. Store this 
data-object on disk, and your API can call that to do whatever 
calculations you need.

Depending on the size and activity of your Repository, you can build the 
"list-of-hashes" hourly, daily, or whatever.
