lexar has more write speed than sandisk extreme but less read speed.
I mean using 1+2 hack on lexar has no different result..

AFAIK, Transfer Function or "LOG" is only applciable to compressed lossy formats (like ProRes, H.264, H.265 ..etc), but not to RAW data.

For H.264 recording?

I don't know if that possible also I don't know how transfer function works (even in MLVApp), but in general someone needs to understand Canon pipeline for image processing, if we are lucky enough it could be there some kind of "transfer function", but again . . someone needs to find from where the parameters could be controlled (assuming if there is a "transfer function").
If there isn't, I think it would hard, for processing speed there are hardware accelerators used for image processing in our cameras, and good luck with figuring out how to use them for our purposes.

You forgot the user. If you setup low-iso/high-iso wrong, preview also doesn't work. But the problem can be one of the 3, or a mixture of all. DualIso is a difficult topic.
For the sun problem: it is not just a DualIso problem - google for "black sun": you'll find this problem with many RAW cameras, even ARRI and Blackmagic have (or had) this. If you like to implement and if have a nice idea: it would be a great new "RAW Correction".

About the pink horizontal lines on dual iso, I've been experimenting and it seems like the white level is set too high on the high ISO part of the image. If I set it to half of the value (white_bright *= 32 instead of 64 on dualiso.c - diso_get_full20bit), in most cases it fixes it completely or at least it gives a constant pink highlighted area, like on the example below.
I'll experiment a bit more, but maybe someone who actually understands the math behind all this can think of a reliable solution that works on all cases and it doesn't affect the general quality. Maybe a slider to adjust white balance individually for the bright and dark parts of the image when dual ISO is selected would help?
