I think this is fine. An informal rule that I follow is if it's unclear, the priority is original > plain > line. This is because original and plain are more common than line => people are more likely to search up those versions.

Hi there,

I'm Devicons' Peek Bot and I just peeked at the icons that you wanted to add using icomoon.io.
Here is the result below (top left):

Here are the zoomed-in screenshots of the added icons:

Note: If the images don't show up, it's probably because it has been autodeleted by Imgur after 6 months due to our API choice.

The maintainers will now take a look at it and decide whether to merge your PR.

Thank you for contributing to Devicon! I hope everything works out and your icons are accepted into the repo.

Cheers,
Peek Bot 😊
