Has anyone done a swap of aam 4.56 gears front and rear?

I believe that the gears for the 4.56 and 4.88 ratios must be chosen from an after market company, Nitro or Yukon, etc. AAM produced only OEM gearing for the RAM and those were the 4.10 and 5.13.
This was the reason I finally made the decision for the 5.13 vs 4.88 and I figured if I went too low then I'd just get a bigger tire. But the ratio is not too low with 35s or bigger (my understanding is with a 35 to 37" tire the 4.88 and 5.13 are very close in engine rpm anyway) .
Also, my gear guy told me I wouldn't hear the AAM gears (he was right but wouldn't bother me if I did, it's usually minimal) and my break in period was "drive it like I stole it" and not 500 miles. He whispered that part. I still tried to be cool w it.
I posted part numbers but I'd be happy to do it again if anyone wants. This was for the 2500 11.5 rear and 9.25 front diffs.
I read what others paid and I woulda much preferred a 2k price tag instead of 2700 that I threw down but I'd do it again every time. The regear changed my truck beyond description, all I can say is If in doubt then experience it and decide. I'd let someone here drive it if they wanted to. (Or was watch me drive it, I do like to drive it lol)
