Should I leave these augments out of "the wolf snd the lamb", or keep
them in?

Sorry. I was going by Greek, where {leipo: elipon leloipa} is
thematic.

Would there be any takers for any plan for people to pool their
knowledge of PIE vocabulary and how each word declined / conjugated
and its likely gender etc, to one list as a start of a compact PIE
dictionary and grammar? Does such a list exist already?

When did the PIE speakers first domesticate horses? The resulting
mobility is likely what started the big expansion and therefore much
ccelerated the change of their language as the usual consequence of
large numbers of uneducated subjected people having to learn their new
rulers' language as adults.
