Stylus nibs for Spin 13 Chromebook?

Hi! I'm looking for replacement nibs for my Spin 13 Chromebook's built-in stylus. Official replacements seem to be out of stock everywhere, and expensive to boot.

I tried my Samsung Note 9 S-pen and it works on the Spin 13 screen, which makes sense because they are both Wacom styluses. My Spin 13's stylus even worked with the nib from the S-pen replacing the original nib, but the shape is not right because the S-pen has a long slender nib, while the Spin 13 nib has a little knob on the bottom, making it a little more substantial and sturdy.

Spin 13 (looks bigger because the phone/camera was closer)

I found these nibs for the Wacom One pen, which look similar with a knobbish rounded end, do you think that they might be compatible with the Spin 13 stylus?

A quick follow-up: someone on reddit/r/stylus recommended that I look for S-pen replacement nibs such as these:

Which are thicker at the tip than the standard S-pen nibs. I've added them (actually, a white version) to my next Amazon order, unless someone has a better idea. So far it seems like nib compatibility is just a matter of nib diameter and length, so these should do the trick.
