All textures in Gun Gun Pixies Steam and Switch version are compressed as .btx. After some research I found that Kuriimu supports this compression and calls it PSVita SpikeChun. So decompressing and recompressing the files is no problem.
Some files in Gun Gun Pixies Steam version have the format SHTXP4 and as far as I checked all Switch textures are SHTXNX which are both RGBA formats as far as I could find out.

The STHXP4 seems to be just normal rgba but with flipped channels for red and blue. I was able to convert it with imagemagick and got this:
Texturefinder:

I wasn't able to find anything for the SHTXNX so far other than that it looks quite similar in a Hex editor but with a different header. I hope someone can help me get these to png or something similar and back.

I found a similar thread but it seems like they were working with the vita files: viewtopic.php?t=8401

Here are some samples:
