Honestly, Lucario seems to stand alone, have no Gen 4 opposite (or any Gen opposite, at that). The only thing I can think of is Lucario being on the Diamond box and Drapion being on the Pearl box.
Lucario is Fight/Steel and Drapion is Poison/Dark, two types introduced in the second gen. They were (at one point) considered opposites. Both their second (and as of now, final) forms were revealed before DP release, and their preevos weren't mentioned at all, they were left for DP.
No other Pokemon is nearly as comparable to Lucario in those categories.
It could very well be possible that we will see a new opposite for Lucario in the next generation (which most likely will be released). Currently, the most likely candidate would probably be Drapion like you've said. I can't really think that Lucario has anything that yet matches it.
