I am not opposed to the idea on principle. However, not all racial advantages would be worth 20sp. Some would be less. Some could arguably be more.
A few thoughts on this...
Currently, each race has 10 advantages. That is, however, a severely incomplete list. Every race has dozens more advantages that will become available to them. Furthermore, we are trying to work on Skill Advantages (also known as Secret and/or Hidden SKills).
Due to the fluidity of this aspect...there is no concrete solution that we can come up with at this specific juncture. Although I am open to any ideas and suggestions.
