Coming up with that many talents per race and have them equally appealing and of equal DP Value and having each race have a distinct set is a tall order. If characters have so much choice , then racial talents are just freebies, not common talents of a shared heritage.

Most racial talents can already be purchased as separate regular talents and some cost less DP's than others. When creating a multi racial character I have actually researched the costs of the racial talents and found that the character could purchase certain ones for cheaper at a later date.
Here are all of the racial talents with their DP costs in parenthesis. Unique (Unq) means it is unique to that race:
Dwarve: Dense Musculature (25), Dark Vision Greater (30), Stone Sense (Unq)
Elf: Enhanced Senses (10), Quiet Stride (20), Night Vision (25)
Gnome: Dark Vision Lesser (20), Natural Camouflage (Unq), Sense Magic (15)
Gryx: Lightning Reflexes (10), Dense Musculature (25), Night Vision (25)
Halfling: Blazing Speed (10), Extremely Nimble (15), Heat/Cold Resistance Minor (Unq)
Humans: Bonus Skill Ranks (Unq), Skill Specialization (10), Profession Adaptability (Unq), Skill Flexibility (Unq)
As you can see the costs are not equal for most of the races and since the unique talents do not have a cost we can only speculate.
TBH I think we need more talents overall to be added to the master list.
The point here is that most of the racial talents can already be purchased outside of a being a particular race. In fact the Gryx and the Elf races do not have any unique talents associated with them so their racial talents are not that distinctive at all.
