The problem of using an average of existing ability scores is that having a high Comliness becomes damn near impossible. Either rolling it seperately (point buy or not), or using some other method would be best, assuming that Com had little to no game effect.
IMC, we use Comliness (with no game effect). We start with 10, and Con and Cha mods. Though it practically never comes up, we've been using practically the same system forever for determining Comliness. The DM I stole it from just averaged Con and Cha, and that works about the same. He also averaged Int and Wis for Perception checks... I fondly remember my dumb fighter never noticing a thing.
But I like that difficulty of being beautiful.
Although, I also really like the adding charisma and other modifiers to a set score. Although, why con, exactly... That's not always the most visible. You could be really pretty and a little frail. Like, say, an elf.
Perhaps it would be good to say, 10 + charisma bonus + your highest physical stat bonus?
"He's beautiful for his strength"
"She's beautiful for her grace (dex)"
"He's so tough (con), it makes him really attractive"
Or perhaps 8 + charisma mod + your two highest stat modifiers, at least one of which must be physical... I like that one even better... You could be hot for your brains and your health, or your wisdom and strength, your strength and grace, or any combination.
Now, for my obligatory comment on the idea the ppl would be wasting time by working on something with no in game effect...
You *do* realize that character background also has no in game effect, don't you? For that matter, Define: "in game effect"
So there are no mechanics really to worry about. It's a thing that makes it fun, and therefore completely worth any "waste" of time anyone chooses to give. After all, I'm almost certain that absolutely any definition of an in game effect will include the fact that it's a game, which can be said to be completely about the wasting of time. Or, at least, spending time in a manner that has no in life effect.

The more time one "wastes" pleasurably, the better the game is.
