I currently can't give you an example (need to go), but you can add multiple textures to swap.
I will provide an example later.
[EDIT]
Right, here is the original:
	"AdonisTMPWarpStartUp": {
		"track": {
			"Plas_glow": {
				0.0: "data/Models/Ships/AdTMP/Luxor/High/Plas_glow.tga", 
				1.0: "data/Models/Ships/AdTMP/Luxor/High/Plas1_glow.tga",
			}
		}
	}
Now, repeat the "Plas_glow": { } part for every texture you want to swap, the names (ie. Plas_glow) is the same type of name as for SDT.
Say you want to also replace the texture data/Mods/Ships/AdTMP/Luxor/High/Sau_glow.tga with data/Mods/Ships/AdTMP/Luxor/High/Clover_glow.tga and then data/Mods/Ships/AdTMP/Luxor/High/cat_glow.tga at 1.0 and 1.5 seconds, then get this:
	"AdonisTMPWarpStartUp": {
		"track": {
			"Plas_glow": {
				0.0: "data/Models/Ships/AdTMP/Luxor/High/Plas_glow.tga", 
				1.0: "data/Models/Ships/AdTMP/Luxor/High/Plas1_glow.tga",
			},
			"Sau_glow": {
				0.0: "data/Models/Ships/AdTMP/Luxor/High/Sau_glow.tga", 
				1.0: "data/Models/Ships/AdTMP/Luxor/High/Clover_glow.tga",
				1.5: "data/Models/Ships/AdTMP/Luxor/High/cat_glow.tga",
			},
		}
	}
0.0, 1.0 and 1.5 are in seconds.
I hope that helps.
