Mind, Body and Soul attributes

I'm just kicking around an idea here till it develops into something<br /><br />the idea is to arrive at a character with ability scores by the player choosing before he rolls any dice the values of mind, body and soul for the character he is developing.<br /><br />if he places a higher value on body then the physical characteristics of the character will be better, if he places a high value on the mind then the mental and if on the soul then the LDR/PER characteristics <br /><br />That's the idea but what the mechanic will be to get there is what I'm kicking around<br /><br />
