Thanks for sharing the link. I buy your theory. That's kinda why I decided to post this. I realized that Ray, as he exists, is like the one percenter version of a Superhero. He has it made with very little effort of personal struggle. (not debating rich vs. poor or whether he's self-made. It's just an analogy.) I just don't think we'll get it on Arrow.
I'm sure he'll have plot development that gives him more dimension and some kind of edge. Just not sure we'll get it on Arrow. Right now, he's perfect and has no flaws. Oliver and everyone else (but Diggle) have more flaws than you can list. That's why Arrow keeps me coming back. Perfect people do not make good TV.
As far as theories of what they could do to make him interesting. I'd love to see it go just as you predict.
The mix of characters announced for the ATOM Superhero spin-off makes me hope it might be based on ARGUS or SHADE. Kind of based on what Oliver is being forced to do by ARGUS in the Flashbacks.
I'd love to watch a show where the government fakes the deaths of all of the characters and destroys their reasons to return to their old lives (or makes it so their loved ones are in danger). Then forces them all to work together and go on missions while using Dr. Stein and Dr. Palmer to develop technology to aid the team and the military. OMAC was being developed for the government so they could easily be watching ATOM right now. Waller seems to know everything so I'd buy that.
With Gen. Eiling on Flash, they are already exploring this direction. In the comics, Gen. Shrieve is SHADE and Ray Palmer founded SHADE so it would be true to his comic story as well, just with a twist. It would be fitting if Ray ended up dead to the world, just like Oliver was. Like a reverse backstory.
If the new team were forced to work for the government it would make it different from AoS, plus superpowers. How else does Capt. Cold make sense? Unless he plays a different character? Recasting 2 known actors in an existing universe doesn't seem plausible. But who knows?
