Well that's not an easy task. Lament's pieces were so rich and perfect for the setting that very few needed arrangements/remixes. Of course, the ones that came with the soundtrack weren't really all that great, so they can only get better.
On the flip side, Curse's soundtrack was made up predominantly of existing Castlevania's melodies and motifs re-worked, rearranged and recombined anyway (...too often producing forgettable, unappealing music) that remixes would pretty much be a moot point. Just a thought.
