Will there be quality loss for YV12-> RGB32 -> YV12 colorspace conversion?

No, it's slightly worse - I would do the conversion back in avisynth . Of course you can just as easily test it yourself. (There is even a sample video above with thin red text) . Whether or not the differences are enough to justify larger HDD storage demands for your goals is another discussion

I tested a bunch of combinations and different sources, and Gavino's suggestion seems the best overall in terms of least deterioration, blurring or aliasing for round tripping it (note there are situations when you may want "blocky" color edges e.g. some types of VFX work , and other times when you want smoother, chroma edges)
