Congratulations comradekingu, you have succeeded where countless others have failed. You have made an ambigram of "Pyra" that doesn't read as "Eyra", "Eyrd", or "Pyrd".
I like the Red one, the first black one, and the two from the second edit. However. Is it possible to make the edges of the P and A extend a little further before banking? That way, the P has a little more of a stem, so it looks a little more like a P. Just a little further should make the P more defined, and if you make it do so by a small enough amount, the A should still read just fine as an A. (Edit: Kind of like the first iteration of the logo you posted)
If we had to have an ambigram for a logo, this is an ambigram I could be fine with.
