Hmm if you do have the time try to find something for the Warlords in china perhaps? I remembered that some of those countries had little. Sinkiang needs many things. min.,leaders and TT.
What about a new TT for Serbia? in late 40s.
South American minors could need something(Argentina and Brazil is done).
The Revloter Siberia could need new miltary land TT.
Its up to you, but the tech team project in general is over.
If you do find something useful and they will make a 1.9 as Gunman_ said, we might use it.
