I need help devising a "reverse Movember"

Last year I did Movember as a joke and people actually donated money!

This year I decided to grow a beard, so I was thinking about making it a reverse Movember, going from full beard to moustache only.

What do you think should be my course of action during the month? I thought of:

1. Fading the beard slowly with a trimmer, while keeping the moustache untouched.
2. Narrowing the beard to a chinstrap and then closing it into a goatee. Finally, moustache only.
3. Somehow slowly making the beard converge into a goatee, by completely cutting it simmetrically starting from the ears.

1 is the most socially acceptable, but it will be hard to see until the last stages. 2 is figured out, but the idea of a very thin chinstrap makes me uncomfortable. 3 is not figured out at all but would be the most visible on the progress pictures.

I need at least 5 phases (one per week + starting point), but ideally more.

Any tips/ideas?
