So excited by the changes Brookshaw has offered so far... ah well, time would still be a factor.
The opportunity to respec the smaller details within the first month if needed would be great.
Happily, we have a respec policy (which I am 90% sure we stole directly from Reno) which allows for this and says 'A character may opt to have their sheet wiped and all experience and starting points redistributed only ONCE in the character's lifetime during the first three months.' It allows for a few other small tweaks to account for mistakes too, and has a few caveats about not allowing you to change fundamental, character defining things... but on the whole I think it addresses what you're talking about.

As an aside, we talked about roster-type mortal and mortal+ characters the other day and I'm going to work on two versions of them this weekend: One would be a 'template' style where you get a brief concept sketch and stats are pre-done, but you can pick your name and make it your own essentially, but is a low-effort entry into things. These don't endure past the player playing them. We're also going to try, as an experiment, a small stable of rostered characters that are a bit more fleshed out, but can be played by one player and then frozen, and then later, possibly picked up and played by a second player. This may include members of the channel 8 news team.
