No. The message response itself determines the encoding and only CP437 terminals can faithfully author CP437 encoded messages. If a UTF-8 terminal user responds to a CP437 encoded message (with non-ASCII chars), the original message text is converted to UTF-8 before it is quoted and the response will be UTF-8. Unless there are no non-ASCII chars in the response, in which case the response charset witll just be ASCII.

I think this question is making false assumptions.

The only encodings Synchronet supports for message text are ASCII, CP437, and UTF-8.

Yes.

The message text would be converted to CP437 before being quoted and the response would be in CP437.

Yup, most software does the same, when appropriate.
