We did this with both our kids; the first one stopped pooping in diaper by 5 months. This made cloth diapers much more feasible as you just have to rinse. A local daycare was willing to do it as well and so she was fully potty trained well before starting preschool at 2 years.

As others have said though, YMMV so don't beat yourself up if your kid won't do it. 80% by age 1 in 1944 is a great data point for what's possible though.
