Description
https://github.com/apache/beam/pull/3333 adds ability to dynamically replace PTransforms but does not support replacements when input and/or output types are different. We have to address complexities due to type hints before supporting replacements with different types.
Imported from Jira [BEAM-2432](https://issues.apache.org/jira/browse/BEAM-2432). Original Jira may contain additional context.

Contributor guide

Define completion as supporting replacements whose input and/or output types differ, including the needed type-hint handling; the payload names no files or tests.
