Well, I still do have the backups of everything I converted. I wonder if it is
  possible to take the repository and get it to some state x (using a
different "move" method by modifying the dumpfile), then merge the changes
from x to HEAD from the "live" repository into the new one I am making, then
replace the live with the new (knowing there would be some revision number
adjustments). This sounds very tricky and "dangerous" though, and I think the
merge would have to be done by creating an incremental dump file (i.e.
svnadmin dump myrepos --revision 1001:2000 --incremental > dumpfile), then
loading the incremental dump into the "new" repository. If I understand
correctly, then as long as I get the tip of the repository into the same state
content-wise, that should work. But even before getting there I have to figure
out how to modify the dumpfile and I'm not sure that can be done easily; what
I need to do is transform the paths of "x/a/b/c" to "x/trunk/a/b/c" for most
paths x.

This is probably too much work, but now I'm still thinking about it from an
academic standpoint.
