This may already have occurred to you, but just in case.

If you contact two of the others, you might be able to arrange a swap. For example, naraht might be willing to swap TC (or another) for Alexander: you'd nominate her choice of TC characters (R, L, Andrew, Alec), and she'd nominate four of the ones you want. My sister is another possibility: she's planning to nominate LotW and MoA.
