Would developers balk at a real-time rating management system on the 360?

First, I love all video games.  Kiddie, near-porn, ultra violent, and so on.  However, I have a young gamer in the house and I'm growing tired of constantly trying to figure out what is *really* OK.  Gears had an interesting setting to remove some of the hardcore blood and language but it didn't remove "shit" and other adult-speak.  Some games will let you turn off blood which is OK, I guess.

I know developers want to see their "vision" in all it's glory.  That often means graphic sex, gore, language, and so-on.  Forcing them to dumb it down would make for some lame games.

The question is this:

If developers were given a standard system on each console where a "setting" would allow a developer to tone down the sexual content, gore, and language for different levels -- say maybe 4 or 5 levels -- would they do it?

Would a game sell more copies if a parent knew they could control the content?  Are the incremental sales worth the effort to develop alternate animations, dress on characters, voiceovers, etc.?

For example:  There are enough games out there like Fable and Oblivion, for instance, that are just objectionable enough that I won't get it for my young gamer.  With a few tweaks, I would...

Edit: whoops, this should probably have been in the "gaming" forum rather than here in the 360 forum.  Oh well.  Maybe it will play out OK.  If a Mod would take 360 out of the title and move it, that would be cool...
