In sum it will be one massive effort and a lot of work and redo all of it when a new update comes by. It also requires FOSE so it needs it's scripts to be converted to NVSE and will need to be converted again with each update of that mod. Seems like that mod is in active development, in alpha stage and doesn't work on any of the DLCs yet, which means that if someone converts it it will only work on the FO3 part of TTW and not on any FO3 DLC, FNV or FNV DLC, which means that who has to convert it also has to make it work on FNV and all of it's DLCs too (and once the get thrown into prison gets implemented also has to implement it for all of the FNV factions that have prisons).
