You cut out one important part of the heist genre: the post-heist getaway or group implosion.
The getaway—fence the goods, cover your trail, get some distance, disassociate from anyone else involved, etc. When it's a group heist you have the whole Simple Plan paranoia meltdown mixed in.
So, in a 10 episode run (this is on HBO, right?), I see it breaking down like this:
Ep 1-4: Conception, assemble the team, plan the heist
Ep 5–6: Execution
Ep 7-10: Escape
I've been thinking about this for a while. My life is great, though.
