That makes things easier. You don't have the same number of vertices in each model, and my above method assumes it did. Wasn't a total waste of time though becuase I can use it for my stuff.
The old ghost method works with a trick though. Don't know why, but objects exported from CShop don't need the trick. Here's the code.

`Spacekey cycles blend modes. mode 4 should emulate old method
`Controlkey rotates models
`cartography shop outputs 2 models
`"standard" way to use these in DBP is to have 2 models, making the lightmap model dark ghosted.
`Am combining models and using blendmapping, although a shader could be used for more flexibility.
`Will work if mesh data is the same apart from UVs
`have left in some stuff that is not required - like 1st index (0/1) in vertcount.
`this is because may be useful if testing this code with models from other lightmappers.

Your models do have the same number of indices though. Think this means they have the same poly count. Counterintuitively the lightmap model has more verts. Maybe you could get a blendmap working by matching up the vert positions, or the polys. Big job though. Perhaps by welding stuff in a modelling program you could get stuff to match.
I imagine you just want this working though. When I read "fused together" in your first post I went off on one.
