Slight problem with that: How are you going to put font and style into a simple icon, e.g. when a “Support me on Patreon” link is put on a page?

I agree with @mybearworld but also wanna mention a few other things - regardless of how much you try to not use a logo as part of a branding it is still the most important element, it will be the thing people see on your app icon, the favicon of your website, the icon people use use on external sites to link to you etc. it's vital you get it right regardless even if it won't be used outside of those contexts.
