I just finished the Pat McGrath lipgloss in Dare to Bare this morning! I fly through these lipsticks, it takes me about 20 days from start to finish (not counting reapplications). Good luck with all the other products! It takes me a long time to get through bullet lipsticks.
I think you are going to do really well on this project as you are great at panning lip products good luck with the purpley one as I think that one would the one I would struggle with the most.
