Briefly, no, you didn't get any mappings to work that wouldn't obviously
work. Based on your mappings at
your successes fall in three categories:
Leningrad, Luther, MT, & NRSV mapping to KJV will work fine because
they're single-translation to single-translation mappings. They're
essentially per-module mappings because those translations that use this
set of versification system definitions use those versifications very
regularly and precisely. (There's actually some slight variability with
NRSV-versified texts, since any translation with either of the verses
added relative to the KJV will be categorized as NRSV-versified. But
that's minor--as is the variance between the KJV & NRSV systems itself.)
These account for 35 of the 53 non-KJV(A) versified translations we
Synodal mapping to KJV will work well for the two Russian Synodal
Bibles, of course. They were the primary exemplars for the system's
definition. I would estimate it will work less well for the two
non-Russian Bibles and rather poorly for the Church Slavonic Bible.
However, there's a chance we'll favor Orthodox over Synodal for many of
these sorts of translations, going forward, so Synodal might move into
the above category of being a single-translation system. (This accounts
for 5 of our 53 non-KJV(A) versified translations.)
Vulg mapping to KJV will work well, to the extent you have defined it,
because you've only got mappings for a few verses outside of Psalms.
Psalms are fairly easy to reliably map to/from because they are
versified in the originals, so there are only two parameters of
variation, each with two possible values (whether to number the titles
and whether to follow Hebrew or Greek numbering of the Psalms
themselves). Thus, there are four major Psalm versification systems,
with far less variation than we see in other books. (This accounts for 9
of 53 non-KJV(A) versified translations.)
The last set of mapping data you have (German) is presumably just copied
from the Luther mapping. I predict it's not likely to work well at all,
especially for the non-German-language texts.
This is all to say that, yes, translation-to-translation mapping will
work great. To the extent that versification system definitions in Sword
reflect a single translation's versification reliably, mapping between
them will work fine. Beyond that, everything breaks down. You haven't
actually approached any remotely difficult cases.
