I'm sorry, but I'm going to have to refuse. The most I can offer is to make the Siren at some point, in which case you could add the existing half-dragon onto the Siren. While I don't mind trying to make homebrew monsters into monster classes, if I don't have a stat-block or even fluff to work with, there's just nothing I can do. I try to stick by the "Number of levels=CR" Guidline we used to go by (Unless I believe it would be detrimental, such as with the half-dragon, or going past 20 levels like with the dragons), but if I don't have a CR to work from, I pretty much have to just roll a d20 in order to determine the number of levels to give a class.

Since I also don't have any fluff to work with other than that it's half a siren, half a dragon, and it's a template...there's really just nothing I can do.
