No, but there would be a learning curve - see
wiki.
If you're limited for time, read up on how to extend M2DA tables without overwriting them - I suspect that's what's causing the character generation issue.
Ideally, it should be an add-in, so that you can enable/disable it on the DLC screen, and avoid conflict with other mods.
You could carry on editing saved games, or write a script to change the appearance after character generation.
If you're a perfectionist, there are many other issues to think about, like what happens after the player changes appearance in the Fade, whether they have the option to revert to their original appearance, how come no one notices they're Darkspawn... which starts to become hard work.
Oh, and watch out for low cielings...
