Rebecca,
Have you looked at Heart of Dakota's Creation to Christ? I know it's author, Carrie, had some of the same issues with myths and gods found in other curriculum that you are finding so she decided to write her own. I believe CTC does teach about these gods, but they do not delve deeply into them.
I have not used CTC, but have been considering it (along with MFW, TQ, TOG, and MOH).
