This is completely feasible but it will mean that pilots lose another skill set.
I agree it can be done but not any time soon in the 737-800 I fly. There is no way the auto- land could cope with gusty conditions with over 25 kts crosswind. ( maybe other types can?)The odd jet lining up on a taxiway would be the least of our worries.There would have to be a technology change before it happens.
