What About Brett Tucker?

Now that we know former Knight Rider star Justin Bruening is Steve Trevor, what about the earlier not-so-important unknown male lead casting announcement for aussie actor, Brett Tucker?

Brett Tucker
It was speculated after his not-so-important casting announcement he might have been Steve Trevor and it made sense for the time because there are only three male leads.  The parts of Henry Johns (then Henry Demeter) and Ed Indelicato had already been cast.

That only left the part of Steve Trevor. 

It begs the question, since the role of Steve Trevor has already been cast, what is Tucker's role in the series (or if he's even still involved at all?).

Personally, I'd still like to see Tucker in the show.  I don't know about his acting but I'm curious how he still fits.
