Your first method sounds actually just like a "usual" WILD technique. When you do WILD, you also visualize patterns on your eyelids, and creates an image from these, until you pass right into the dream.

The second one needs to be validated for me to believe in. Even if being insanely good at AVC, I don't believe you will have the overview to create and uphold every little detail. If you do not do this, you are not able to dream from the start, since we first enter NREM. People who is able to enter NREM often ends up in blackness, but with the feeling of being in a dream, as far as I have read. So you would have to wait until your body hits REM. The second technique just sounds amazingly hard. Someone might prove me wrong, but I don't think it is possible to create dreams from the start of the night that is lasting for more than two minutes.
