Bob, I was able to fit two 6 ft. romex cables inside a 1/2" flexible
conduit with no problems. There is still plenty of space left. I can't
use Romex only because as far as I know, the local code doesn't allow
the use of Romex cable in high rises.

You're misinterpreting the Code. The National Electrical Code doesn't permit
the use of Romex *anywhere* in *any* building that exceeds three floors above
grade. Unless your local enforcement authority has adopted a specific
exception to this prohibition, you're violating the Code to use Romex, whether
it's inside Greenfield or not.

While I see this as a very likely possibility, the law itself is
really stupid when you think about it. If it's inside greenfield or
steel conduit, it's in accordance with the code. Whether you use
single wire or romex, the wire is the same thing. Actually, the romex
has more insulation around the wires, so you'd think it would be
better insulated (although not necessary). It's things like this that
often make me wonder who writes these codes....
