One of the options in my "things I'd do differently" post was multiple PCs per player. Not just multiple 250-point guys on hand in case you guy dies or in case you want to play a higher or lower point guy. Another option I've considered is to rather have "main" and "secondary" characters you could run at the same time. Here are some thoughts on that approach.
I picture this working as follows:
- you'd have your high-end, "main" guy. This would be your primary character. You'd run this paper man most of the time. You could, of course, have a secondary 250-point guy.
- you'd also have an associated 125-point guy. You could run this one as your only PC for a session (and earn full XP for it) or run it as an ally - running two PCs - and get half for that character. The secondary character would need to be exposed to real risk, but could progress up while getting bootstrapped in a way by other players.
You could always take an Ally as well, and get the lockstep improvements of the Ally on top of having another, lower-point PC to run.
Another option, I think, would be to allow multiple 125-point characters to count as one, as suggested in DF15. That seems like it needs no additional detail than I listed there.
Encouraging Ally might be something else I could do - make it advantageous to find specific NPC hirelings and add them with Ally. Assured access, increases in value as you increase in ability (gain and spend points), and assured loyalty (instead of a secret Loyalty stat) would be some of the benefits. And for low-point guys, this would be fairly cheap. That might not grab everyone, but could allow some players to expand a pool of playable characters and make each of their characters potentially more powerful - you'd have your own crew to draw on if you needed to pad out an expedition.
