Ooh! Yes!!!
I've been wanting to start this up again too but worried that you're having too much fun in the jungle. Plus I have one or two other things going on this week so wouldn't be able to really get back into it until near the end of the month.
I think (but not sure yet) I'd like to keep going with my own story arc. I started to like the idea that I was shaping the story arc, instead of having 6x people all muddle around with completely unaligned goals. It's more like computer RPG instead of tabletop RPG, but there's something weird about PbP that I'm not quite accustomed to yet. Maybe it's just been the PbPs that I've been in. Imagine if Tolkien's Fellowship all wanted to head their own directions instead of acting toward a common goal; or if Arthur and Lancelot split up over whether to find the Holy Grail or just attack Mordred.

Also, posting speed is a LOT faster when it is just the two of us. I don't like the PbP games where dice gets rolled (something variable happens) only weekly.
I was half-thinking something very similar to your retainers suggestion, but with a slight twist. It's been a while so I've forgotten some of the details -- bear with me! -- but remember that abandoned keep where the party got pinned in the tower by the goblins? I don't think I can afford this quite yet and was planning to wait for level 5 because I have a self-imposed halo around level 5. Plus, winter is coming. Enough caveats. Here's the idea:
Start turning that keep into a base of operations, and work out a supply line between Red Oak and that fort. Hire a few dwarves to start improving the place, hire a few guards (ok a lot) to scare off the goblins, and ask the good shapeshifters (Luscha, sorry about the spelling) if they want to view "human" culture firsthand. Maybe even Anna's da has a skill that can break his alcoholism.
I know it's a stretch with the current state of the characters' levels and finances, but it has still been bouncing around in my mind.
Here's the two issues where I got stuck on the current game and why I got bogged down. It's mainly my doing, but I kinda boxed myself into it because I had thirty days of gear and planned a serious spelunking operation. First, it turned into a dungeon crawl and the party was seriously outgunned. Yes, attacking a tribe of goblins isn't a good idea. I know you said "go deeper" but as any dwarf knows, the deeper you go the worse things get. That means neither up nor down were great options. However, I couldn't completely let go of exploring the whole area because that was my best lead on "something interesting is happening!" opposed to aimlessly wandering around the wilderness. Not that I mind the wandering part, but it was more the story and background threads that draw me to this game opposed to a more simplistic "wander around, kill stuff, get loot" campaign. So kudos!
My second problem was, I don't know much about the Old Man. He did a great job covering his tracks, and all I recall knowing about him is that he's out to get me (you said that; I don't think I learned that); he's in league with the Nisha; and he's trying to find something in the mountains. I have forgotten some of the in-game knowledge on that last point, and would read up on it once we start up again. Overall though, I understanding of the Old Man is about as much as Frodo's understanding of Sauron right before he leaves the Shire.
Let me think about it for a couple of days and then kick off a discussion with Anna and Bruce. They (you) should definitely get a chance to figure out the next step as well.
Wow! That's a lot more than I thought I'd write. To answer your question, yes I want to keep playing.
