No. The existing, client-to-server semantic of Accept-Encoding is "For the response associated with this request, I will accept the following encodings..."

In the server-to-client direction, the proposed semantic is "For some unbounded set of future requests, I might accept the following encodings..."

There are a number of subtle differences there, especially about the scope of applicability -- one of the most ill-defined areas in HTTP metadata.
