If Atahualpa isn't capable of having child themes, can users still switch th

I'm gonna be blunt and ignore polite speech here, because I've been screwing with my theme all day, frustrated that I can't solve some simple problems with my site. I am in a bad mood. I started using Atahualpa yesterday, and I have a serious gripe with it: no child theme support. Everyone keeps repeating the ideal that Atahualpa is "too good" for child themes, that they are unnecessary for several reasons. But I don't care.

I need my theme to have an ability for my members to switch specific styles. Nothing special, just a few colors and images-- and a emphasize that. Essentially, a really basic theme switcher. But apparently, since Atahualpa hates child themes, I have to figure out some special way to do it. What the heck.

So is there a way to allow my users to switch some colors and images with the click of a button, like a theme switcher plugin would allow, or do I have to get a new theme? Because that's what's gonna end up happening if I don't have some kind of solution. Can someone please help me?
