Since umodel license has been updated on 07/01/2022 to MIT (https://github.com/gildor2/UEViewer/blob/master/LICENSE.txt) which allows to distribute it, it can now be directly integrated into UT Convert, so user would no longer have to configure it.
In a second time it would be possible to fork umodel to be able to read unreal 2 texture for example and add extra features maybe some direct interface with java via JNI (Java Native Interface)
