I'd really recommend a transfer switch as a safer installation.
This is basically a specialized breaker panel which allows you to
hook a circuit to exactly one power source.  Some even have ammeters
to assist in balancing the generator load.  Your idea is simple but
has a couple of opportunities for operator error zapping you big
time - get the sequencing wrong and you've got generator attached
to the grid for some real fireworks (a padlock on the main switch
would reduce the likelihood of someone else doing it).  You also
need an extension cord with a male plug on both ends presenting
a serious shock hazzard!
A transfer switch is in the $100 to $300 range depending on the
number of circuits.  If you need the electrical installer, the
total cost is obviously more.
