What type of new 50mm f1.4 lens you want from Canon?

Canon 50mm 1.4 is an old lens and needs o be updated according to many users. It is an older design where the lenses are somewhat hazy at the largest aperture (due to spherical aberration) and gain contrast by stopping down to f2 and beyond. Other lenses of similar design are Zeiss Planar T* 1.4/50 and Nikon 50mm f1.4G, they show similar characteristics. But the advantage of these lenses are, they have fewer optical elements and so they are light and small, and are relatively cheap.

On the other hand there are modern 50mm lenses from Sigma and Zeiss, which are better performer at wider apertures. These lenses have more optical elements to correct spherical aberrations and so they are heavier and larger, and pricier and much better performer at wide apertures.

Here is a comparison between these lenses:

Lens - No. of optical elements/ groups - weight

Nikon 50mm 1.4G - 8/7 - 280 grams
Canon 50mm f1.4 - 7/6 - 268 grams
Zeiss Planar 50mm f1.4 - 7/6 - 380 grams

Zeiss Otus 55mm f1.4 - 12/10 - 1020 grams
Zeiss Milvus 50mm f1.4 - 10/8 - 922 grams
Sigma 50mm f1.4 Art - 13/8 - 815 grams

One example of older design lens vs newer heavier better performer replacement is Zeiss Planar 50mm 1.4 vs Milvus 50mm f1.4.
So what type of new 50mm f1.4 lens you want from Canon? Older design, moderately priced, light lens (though of course comparatively better performer with better focusing than the current lens, because otherwise there would be no point of releasing a new version). Or a newer design, larger and heavier and much better performer at a higher price point?

Since it's almost Christmas time, so I have a wish if Santa or Canon can bring me a new 50mm preferably in a F1.2L version with the edge to edge sharpness of the Sigma 50 Art and Bokeh of the Zeiss 50 1.4 Milvus. No focus shift like the one I sold a while back please, I don't care about size and weight, in fact, I hate small and light  plastic lens so anything like the Sigma or Zeiss will be perfect, oh, yes, I am prepared to see a high price tag for such lens, it won't be a cheap one but it will be a great one.
