I think you'd have better luck with some kind of a glider launch system where you have a stationary motor on the ground and a long cable. It's possible to put 2kft of altitude on in less than a minute this way. If you wanted to do the same with GA electric planes you probably could perhaps with longer runways or more powerful winches esp. if you engineer the airframe to handle a more powerful winch. https://en.wikipedia.org/wiki/Gliding#Winch_launching https://en.wikipedia.org/wiki/Gliding#Winch_launching
