Hello!
I see you have problem with compatibility after crpg updates. And I see it's because item_kinds1.txt changes after it. I made programm (on C#) for my crpg submod
http://forum.c-rpg.net/index.php/topic,23362.0.html which can parse item_kinds1.txt and replace items and models automatically. After every crpg update i just run it and my submod works again. I can make programm which will correctly install your mod. It will parse item_kinds1.txt, module.ini and copy resource and textures. It will have progress bar and screenshots. For update your mod you will need just edit two xml files.
Like this:
1st xml with models:
<model id="new_masterwork_sword"/>
<model id="new_another"/>
....
<model id="new_another100500"/>
2nd xml with replaces:
<replace_item from="Masterwork Sword" to="new_masterwork_sword" />
<replace_item from="Old Another Item" to="new_another" />
...
<replace_item from="Old Another Item100500" to="new_another100500" />
I can make first version of this installer in this weekends. After i make it, you can update your mod without me, just edit xml and replace your resourses. Then zip it and publish.
I hope you interesting in my offer, because i want to play with models that you made, but i cant, because "Current cRPG updates break the mod" )
Sorry for my english, i am russian speaking man )
