I'd buy those in a heartbeat. While I'm a white dude, I live in Texas where Mexican culture is a HUGE part of the overall culture. I was introduced to Dia De Los Muertos as a teen by a friend's mom, when I asked her about the cool little skeleton dudes she had on display (previously, I'd seen them on the cover of Oingo Boingo's "Dead Man's Party" album, but didn't know anything about them). Mama Rosie, as I called her, sat me down and taught me ALL about the holiday and its meaning. I loved it! It's a beautiful holiday with a fantastic meaning behind it...and cool skeletons! I have a modest collection of sugar skulls and little porcelain figurines that I put out right after Halloween. At one point, I was a little worried my Hispanic friends would think I was appropriating their culture, but they've all told me that the fact I actually observe and honor the holiday itself in a respectful fashion makes all the difference.
I also really dig good Mariachi music, so figures with cool skeletal swappable heads would be in my wheelhouse 100%.
