The TWOT numbering system is linked to the Strong's numbers in the hard-bound volumes. Also, the Blue Letter Bible web site shows the TWOT reference number associated to the Strong's in their Bible Tools, so it can't be an impossibly difficult task to do. I wish someone with the skills would provide both the TWOT and TDNT (unabridged) as a module for purchase for e-Sword. 

They can't be downloaded for free anywhere that I've found, if that's what you're asking. I purchased the hard-bound version of the TWOT and am very grateful to have it for my Bible study. I haven't been able to purchase the 10-volume set of the TDNT as yet due to budget constraints. I found a site that sells an electronic version of the TDNT for $199, which is almost $50 more than the average price of the hard-bound TDNT.

With respect to availability for purchase in some of the Bible apps, the TWOT is available for Olive Tree, Logos, and WORDsearch, to name a few. I primarily use e-Sword and Bible Analyzer as my Bible apps, but downloaded WORDsearch as well expressly because the TWOT was available for purchase and use in it. I haven't seen it as being available for e-Sword or Bible Analyzer. 

Hope this helps a little :-)
