Mm, you'd actually have a better chance of ledgegaurding him with an f-tilt or even a forward-air depending on the degree of the downward angle.
Luigi's d-air hitbox goes further straight down than horizontally, so while it is an almost unbeatable ledgegaurd when using against an upward-angled firefox, it's not so useful for downward-angled firefox towards the ledge, because the horizontal range on it isn't quite good enough to hit fox before he gets within grabbing range of the ledge.
but yeah, that situation is probably the hardest for ledgegaurding. If you're too close to the ledge, fox is probably gonna go high and over you while you pointlessly go for an aerial at the ledge, and if you're too far away, he'll go straight to the ledge. So yeah, you're best bet is probaby the f-tilt, because of the range and quickness. Because with f-tilt, you can stand a good enough distance away from the ledge to let the fox think he's safe to go for the ledge, but then all you have to do is a fast WD towards the ledge and f-tilt him before he reaches the ledge. While at the same time, you're also covered if he goes high, because you're not right near the ledge trying to do a risky aerial, so you have time to just WD back and punish him before or during his land (preferable before)
ledgeguarding fox is like almost as fun as ledgegaurding falco though lol >_>
