Fey Touched ? [FF]
LA +1, but its a pale shadow of Half-Fey
Other than that the Fey templates are all high LA, low value.
Though there is the Unseelie Fey template, but that is missing an important detail ─ so YMMV
ED: Savage Species split the Half-Fey template into 2 racial levels, so you could also just apply one level of this ? Its available online, here
