N64 Texture issue

I've been ripping models from Perfect Dark using Lem's 3D VRML exporter, The models work fine, but there's an issue involving some of the textures.

The K7 Avenger uses a double-texture layered format to use the shine effect some N64 games use, and also has a transparent texture on-top to allow both a shiny and textured model.

Some graphics cards don't support layered polygons that well, so both of the textures blend in like a mess.



For reference, here's a screen capture of the model in-game:



I later on thought of editing up the textures so that they merge the transparent and main textures into one final texture of how it is rendered in game. And removing the layering of textures.



But, I feel like this does not make it a legit model rip, since I edited the model up, or would this work and be allowed?
