that way you would even have it twice in RAM!
Once as compressed and once as pixmap as the pixmap will exist until the image is null-ified
so that would definitely be the worst idea.
What people were talking above is actually real hardware compression. S3TC / DXT. that is small on disc and remains as small in VRAM. Benefit of it is faster loading time and pregenerated mipmaps if you want to use them. They drastically reduce loading and upload actually and raise the FPS due to that (as texture binds are faster as well)
