Crazy idea but since the paint mode is already special cased, if you check IsCsgLoaded is false, set visual style to default you can use the spinning mouse car as is.

            "frames": {
                "flat": true,
                "gentleSlopes": true
            },
            "hasAdditionalColour1": true,
            "hasSpinning": true,
            "hasAdditionalSpinningFrames": true,

    "noCsgImages": [
        { "path": "images/preview.png", "format": "raw" },
        "",
        "",
        "$RCT2:OBJDATA/WMSPIN.DAT[3..4610]"
    ],

That seems a bit too dirty for my liking. Especially since setting some of those flags will affect track piece availability and TD6 export/import.
