How Insane would it be?

 How insane would it be to collect and paint an entire Space Marines Chapter, say, for example... the Crimson Fists?

Very.

And yet, I am actually considering it. Let's look at the numbers, shall we, assuming that each Marine etc., has only one usual role (Intercessor, Tactical, Devastator, whatever). I will even reduce squads within companies in order to provide crew for attached transport (but let's face it - isn't that really a job for servitors? Space Marines fight, they don't drive trucks.)

In all, that's something like 1,174 Marines. Plus vehicles. Maybe that is crazy. I think I will just stick to filling out a full company as a goal for next year.
