Ok So You Know How X-sexual Y-romantic Flags Are Sometimes Done With The -sexual Flag As The Background

ok so you know how x-sexual y-romantic flags are sometimes done with the -sexual flag as the background and the -romantic flag as a heart-shaped overlay? like, asexual biromantic would look like this:

and i find that to still be kinda sexual-romantic only centric, so i'm wondering if we could come up with different symbols for other kinds of attraction, like aesthetic, sensual, platonic, alterous etc and one for undefined. and maybe a sexual one too if people want to have a romantic flag as the base? i think this would be cool. i just don't know what symbols to use for different types of attraction, especially because i don't really define mine beyond just tertiary/non-rose.
