Using --geometry flags (or any -o <override> argument) on the command 
line means that MythTV will not--even after going into Appearance 
settings--use the size specified in Appearance settings, since it says 
to ignore the database setting no matter what (even if you change it 
during the session).  If you really want command-line changes to your 
settings, you'd actually be better off using the services API to change 
the setting then start mythfrontend.  Just have your script issue a 
couple of curl calls, like:

curl --data HostName=<frontend_profile_identifier_or_hostname> \
      --data Key=GuiWidth \
      --data Value=1280 \
      <backend_address>:6544/Myth/PutSetting
curl --data HostName=<frontend_profile_identifier_or_hostname> \
      --data Key=GuiHeight \
      --data Value=720 \
      <backend_address>:6544/Myth/PutSetting
# Then start mythfrontend

It would be easy enough to do with a single script that accepts width 
and height arguments, allowing you to start with any size screen from 
the one script.

Overrides are not meant to be used during normal usage.  They're meant 
to override broken settings to allow you to get into settings and fix 
your system.
