I could be wrong, but my understanding was that you had to actually takeoff for the taxi time to count. You could taxi around for an hour, takeoff and do one lap around the pattern, and log the entire time as flight time, but since you switched planes before taking off, I don't think it's flight time.
From FAR 1.1:
Flight time means:
(1) Pilot time that commences when an aircraft moves under its own power for the purpose of flight and ends when the aircraft comes to rest after landing
The fact that it says "after landing" seems to imply that you had to actually takeoff.
