Couldn't you just swizzle the value in whatever shader you use? Or you could use EXT_texture_format_BGRA8888 or APPLE_texture_format_BGRA8888.
Also, an optimized BGRA<->RGBA conversion is about the same cost as a memcpy, so if you have any memcpys you need to do you could possibly replace one with the conversion.
