Slabtroller - I stuck a few molds last night, and came up empty for you too. The smallest I can get a complete mold using a #2 hook is a 1/48th oz. minnowhead. But I noticed something that you may want to keep in mind:
If you are looking for a conventional head on a #2 hook, it may not happen. I use either Eagle Claw, Mustad, or Gamakatsu hooks - all of which are too thick to get a complete form around in 1/80 and 1/100. I had to make a temporary mold for these two sizes, as the eye to bend distance (#2) is too long, and the hook diameter too thick to fit commercial mold cuts. (and I didn't have extras in these sizes to take a Dremel to)
However, using a roundhead with or without collar was a challenge. It can be done, but I had more failures with exposed hook within the mold then I did complete coverages.
Tried all the hook manipulations I know of to fit oversized hooks, but this just wasn't happening. I can fit a 3/0 to a 1/8oz head, but not a #2 to anything in the sizes you are looking for - go figure?
Maybe using a thin wire hook would help?
The other option you have is using thin lead/bismuth wire and wrapping around a bare hook to the weight you want?
Sorry I came up empty for you.
