I have 0 opinion on a light or switch though, I only wanted to address that one concern that you voiced to try and explain why it has to be that way.

Well, it sounds like having an override switch activated would be a bad (possibly very bad) thing if the trans wanted to downshift out of OD, then. Trouble is, though, it's not just an OD --> unlocked --> 3rd shift. It seems like it likes to stay in the unlocked condition too long (or at least longer than I'd like it to). As soon as I see the tach jump, I hit the OD button, and knock it into third. Maybe I'm exhibiting some "conservative-ism," too.
Regardless, that pretty much seals the deal against the switch for me. The light OTOH, couldn't hurt anything.
Thanks.
