Honda recommends changing the tranny fluid every 30k. I change mine once a year, its cheap insurance. It is also incredibly easy. I can change my tranny fluid faster than I can change my oil.
Most of the people that I see that still use honda mtf use one of 2 arguments... 1 - it is good enough and/or 2 - its cheaper than redline. If people say #1 then you can't argue with that. If they say #2, then they are just being silly. In the case of a civic, we only need 1.9L of fluid. So the extra $10 spent at fluid change time on redline really shouldn't be a big deal. I've never seen anyone complain about using redline (or gm synchromesh w/friction modifier for that reason).
As for mixing mtf and redline... I'm not a chemist so I would never try. Ever seen what happens when you mix 2 different oils (of any type) ? They separate plain and simple and you may not even get the same protection that you would have if you just filled the tranny with the lesser oil/fluid. here is an example of what can happen when you add an additive :

Moral of the story here is don't be a backyard chemist and try to outsmart the folks who made the oil/fluid. Pretty safe to say that they know more than we do.
