I'm a ginger who wants to mix my ABH Caramel powder with Glossier's clear Boy Brow so I can have my own version. How terrible of an idea is this?

As a ginger of northern European descent I'm used to companies not making eyebrow products that cater to me. Most "auburn" products have too much red and not enough brown/orange in them. ABH's Strawburn was pretty much perfect but they discontinued it in favor of Caramel, which I'm still salty about.

My brows are blonde, but I've found that blonde brow products don't really give me the look I'm going for. They're also fairly sparse, so I usually need to fill them in on the daily. Right now I use the brow powder duo but I'm going to start going to the gym before work (pray for me) and I need something that's even quicker, easier, and takes up less space in my bag (1 product instead of 2).

I've heard the Glossier Boy Brow is better than the ABH brow mascara, which is where this harebrained idea of mine comes in. Does anyone have any tips, tricks, stories, or warnings to share? I'd love some feedback!
