Update mapping to support an additional date format (without reindexing)

Elastic Stack Elasticsearch
1

Is it possible to update my document mapping to support an additional date/time format without having to reindex?

ie my current format is:
{"type": "date", "format": "yyyy-MM-dd HH:mm:ss"}

and the format I want to set is:
{"type": "date", "format": "yyyy-MM-dd HH:mm:ss.SSSSSSS||yyyy-MM-dd HH:mm:ss"}

Given that the current documents will still be valid I expected to be able to do this, but when I try I get a 'conflicts with existing mapping in other types' error.

Is this expected behaviour? I'm using Elasticsearch 6.6.
