and the result was an average of 9 rasterlines gained. best case from the stream gained 7 rasterline, and worst case gained 11 raster lines.

Also tried this out:

Just an idea to take advantage of this:
for walls between 63 - 48 use downscaling of 64px texture with longwords where possible, and for 47-33 use mipmap upscaling of 32px texture with longwords where possible.

And it did result in better visual quality (see attached picture) without having and impact on performence.

So by using these two improvements the demo is now a tiny bit faster, with overall better visual quality.
