I've thought about it, but haven't done it. Most such airports are
scraping to stay open as it is. Running the lights isn't cheap, and
every 15 minutes they are on costs a fair bit. Doing what you suggest
is inconsiderate at best.

Actually this came up one on another group I post to and it led me to
doing quite a bit of research about the cost of runway lights. I learned
some interesting things about runway lights. The long and the short of
what I learned as it relates to this is that turning on the lights for
15 minutes is just going to cost the airport a few cents in electricity
and maintenance. If they are using LED runway/taxiway lights it's going
to be considerably less than a cent.

I will admit that my research did not include approach lights, so it's
possible that they burn more electricity and cost more to maintain. Also
one problem with LED lights is that they give off so little heat some
airports install thermostat controlled heaters with them to melt
surrounding snow so it might cost a bit more to turn them on on a very
cold night.
