Monster/Racial Class for Half Celestial?

[The_Universe]

Is there a savage species style Monster class for the half celestial anywhere out there? The +4 level adjustment is a little high, but I don't want to forbid it, out right. Is there a book (or an enthusiastic amateur) that's split the +4 LA into class levels?

There's an Aasimar/Half-Celestial transition class:

You start off as an Aasimar and, over 3 levels, gain the Half-Celestial's abilities.

There's also a zero-level Aasimar here:

I haven't compared this progression to the template to look for any differences, but it looks pretty close.
