I don't know of anyone who has done it or considered it. I would think, its probably going to be an expensive conversion.
FWIW I have considered putting a 4L80e in my vette. I have one, but even at that, the tailshaft conversion kit is $600.00 a controller would be $600-900.00 dollars, and then there is the converter. By the time I upgrade it would run a min. of $2,500.00 in parts and probably more. Unless I really start having problems with the 4L60 not holding up to the power, I will probably stick with it.
Again, FWIW it seems there is more information out there for doing the opposite. Taking the 6L80 out and putting in a 4L80. I assume it has to do with strength and available aftermarket support.
Never the less, if you do it, I hope you post progress reports and let us know how it works. It sure sounds like a good idea to me, if the cost is not too much.

I have always heard this as well, but would like to see documented proof of it being true, and if so how much.
On the other hand, the 4L80 offers a closer gear ratio, so the drop from 1st to 2nd is not as much.

Sometimes with strength comes weight
Didnt TCI have a 6 spd auto out? Pricy
6 spd auto with some gear and a little converter could be a lot of fun
Not sure if it would sway me from a stick but more going on anyway.
