Are there any plans to re-extend Metropolitan service between Amersham and
Aylesbury?

Very unlikely. There have been two occasions when something of the sort has
been considered. In the early 1980s there was serious consideration of
closing Marylebone, transferring the Joint Line service to Paddington, and
making Aylesbury passengers change at Amersham to a Met train. AIUI a major
reason why this was rejected was that the Met couldn't cope with all the
passengers who used Met line trains into Marylebone.

Later, the first iteration of Crossrail involved a spur to take trains on to
the M&SWJ north of Acton Wells, then via new trackage at Neasden on to the
"Chiltern" Met Line. There would have been 25 kV OHLE through to Aylesbury,
and Crossrail would have taken over the Chiltern Met Line and the Met
Amersham and Chesham lines, leaving Baker Street with Watford and Uxbridge.
This was rejected largely, AIUI, because there are insufficient passengers
from beyond Amersham to Aylesbury to justify electrification.

On top of this, TfL, as an emanation of the Mayor of London, only has a very
tenuous remit beyond the boundary of Greater London.
