Of course it's useless!! IR port is not a camera!! nor an illuminator!! And Sony led has probably a different wavelength. Or can simply be a double one with red+IR. Btw the problem isn't the led but the filters you might remove. so, if someone has IR leds, can I suggest to try to get some pics? so we can see how much we need to fight for removing the filter. this is what you should expect with a standard digital camera hacked: (a friend did this)
