Talking about code it is possible to build a community website not using outpost but it will always take time to do a proper frontend ensuring that everything it is correctly working.
In my opinion maybe we will not have that concluded fastest enough.
When I said to start with outpost it was to be able to start the ads in the front end from day 1.
About create a costumo community without a token and afterwards launch a token I think that is possible at least I never heard anything saying the opossite.
There were meant to be ads included with outposts as part of the package but they were never properly implemented. How much work would it be to add them manually to the outpost from day one?
If your serious about creating a project it might be worthwhile making a discord channel and inviting about 5-10 of us to see where the discussion goes.
I think that the people listed in the post are some good people to get started.
Since I have an It background and I am already looking to this with a friend mine that is also an hive user.
If you want you check here an outpost frontend running by us where we are doing testes to see how ads will be displayed

I have already though about creating a discord to everyone be able to discuss and see each opinion.
I will create a discord channel and contact each one to see if they want to join the group
