Make your cube first then get feedback from your drafters, its much easier to fine tune your enviroment than theory craft it. The best way to make a cube is just to build one with what you have and develop it over time.
Cubes work with any ammount of people, the decks might just be a little less refined due to not seeing all the cards.
To be honest I dont mind haveing a large undrafted section, it helps variety a bit since not every card shows up in each draft.
We regularly play with 2-4 players from my ~450 card cube with a mix of sealed and draft. We used to do do "pick 1, ban 1" but decks, whilst more streamlined, lacked variety.
