I’m not necessarily looking for a quick fix/easy grab, but would be interested in getting the changes you describe merged in the main codebase. That way we advance the state-of-the-art and avoid fragmented development, which I believe is very valuable.
If that is something you can agree with, perhaps we can find some way to work towards those goals.
One possibility I see could be for Xamla to apply for a ROSIN FTP. That way you could be (among other things) financially supported to work on the driver.
If that would be of interest, contact me off-list and I can provide you with more information.
