Having done the same thing on Blue, but with a twinked Cleric, I feel like you missed out on a real opportunity by not doing Tower of Frozen Shadow: the first couple levels of that dungeon are
perfect for a soloing cleric.
(The higher levels probably are too, but CRs start getting hairy ... in fact, even the second level can be a bit of a pain if you don't corpse a key in advance, or have a high level alt handy to kill the 1st floor key mob.)
If anyone is thinking of repeating this, and not desperate for plat, I'd definitely recommend TOFS over Misty Thicket (for one thing, halflings aren't undead
