Well, not to burst your bubble… but the direct method I was thinking about doesn’t work… you can’t access the level BP from any other BPs directly, so the “expose variable” thing is out. I did find several other suggestions of ways to do that sort of thing, but they were all clear as mud (and I don’t have time to try and sort them out)…
But, I’ll be checking back here to see what develops, as I’m sure at some point I’m going to need to transfer data between levels somehow, which kind of requires being able to chat with level BPs in some way…
