Ehh 10th isnt that far off of a 6l80's 6th at .667. I think an LS JK with 4.88 and 40s wouldnt have an issue with the .037 difference.
There is no question mark at the end of your sentence so you made a statement that it would be a good candidate for a swap and not ask if it would be a good candidate.
The whole point of having all these gears in a transmission is to try to keep the engine in its optimal rpm range. With the new direct injection engines, that optimal band is actually pretty broad so 10 gears is overkill. They did it for fuel economy. I would venture a guess that while four wheeling, that transmission would be doing a lot of searching between gears. I think the 6l80 is more than enough trans for a Jeep.
I agree with you I think the 6L80 is about perfect for a JK. My 10 speed usually skips a gear on every shift unless under a load. Usually 1-3-5-7-9 & 10 on a light throttle cruise. It's a lot of gears for sure. The 4.69 1rst gear is great for good starts.
