I've been trying to do this, HIIT on the bike, followed shortly after by weight training (experimenting w/ GVT). Personally, since I don't have great endurance b/c I don't do cardio, its not been working for me since I feel worn out by the HIIT that it I don't lift as effectively. Perhaps its something you just have to experiment with, and build up to.
