Question: would someone who currently has an SER annual season ticket issued
for travel between a station within Greater London and 'London Terminals'
only (i.e. no bus or tube travel at all) end up paying more or less for
their weekday only, peak hours only travel to and from London if Oyster were
introduced at SER-served stations?

Either the same or less. You'd have a choice between renewing the
season, or using PAYG each day if that works out cheaper.
