I doubt they they could get the amendment ratified in 2-3 years even if it was uncontroversial (which obviously this is) Technically it can be done in months. Just getting 2/3rds the house seems unlikely as there are more democrats than that (and it isn’t clear the republicans would agree to this - Trump is past the first 100 days and the house is as normal looking at the winds for the next election), Then 38 states are needed - Trump didn’t win that many, and it is also not clear even the states he won would agree.
