If I recall, Aiko LE has no injection channels (the full one does), so your sorta out of luck on injecting your character. I don't see any problem on redistributing the LE CR2 as a base for your character, though, this is generally allowed, bearing in mind IANAL, I suggest contacting DAZ 'bout it. At the very worst you could RTEncode it using the original as a key. I don't see any other way for you to do it.
