I don't think you can use Windows 10 offline images, using Windows 8.1's DISM, it has to be Win10's DISM. But you can copy the files to the ADK folder so that it will work. Scratch that, I tried Win10 DISM in 8.1 ADK folder and it couldn't run, needed additional files!
There are DISM and ImageX 6.4.9841 on Windows TP ISOs, but these two programs are only a part of Windows ADK.
