different domain = less authority, but maybe it's good enough

Compare your sites metrics with the metrics of your competitors already ranking for duplicate press releases.
Post some press releases and monitor closely which press releases are indexed (multiple granular sitemaps and WMT) and which press releases rank.
Throw links on the press releases if they don't rank to find out if ranking is possible and just a question of link quantity/quality.

How to reach the best possible (technical) quality is another question. Maybe you can find some inspiration in my latest thread: [webmasterworld.com...]
