I brought this up back in February, I thought I raise it again.
What about adding Jastrow's Dictionary of the Targumim,
the Talmud Babli and Yerushalmi, and the Midrashic Literature?
It's online in .pdf form from Etana.
I assume that means the copyright has run out, but I don't know.
Given the addition of the the Targumim and DSS, this would be a great addition.
How much interest is there?
