Aasimar?

In Pathfinder, they're called "Suli"

kind of, but they are not quite the same thing

I would like to see a form a genasi, knowing they can't use the name

Water genasi are mentioned as "maridar" in The Great Beyond. Shadow planetouched are known as "fetchlings" in the same. I may have mentioned other groups of elemental planetouched as just that, 'elemental planetouched' without giving a specific name for them (or in a few cases I goofed, used genasi in the original manuscript and thankfully had it edited out).

As Asimars are +1 LA anyway you can jst use them as is. Just change their +2 bonus on listen/spot into a +2 bonus to perception.
