Sorry, as far as Tri-Ace has officially stated, or hinted at unofficially, there isn't a remake in the works. It's a shame, since this game goes fairly unnoticed.

However, if you're trying to follow up with your Valkyrie Profile business, there are appearances of characters in other Tri-ace games.

Semi-Spoilers for Star Ocean 3 and Radiata Stories.
(SPOILER) In Star Ocean 3, after you complete the main story, you run into a chibi version of Lenneth Valkyrie in the Maze of Tribulations, and again multiple times, and finally fight her in Sphere 211. Both Gabriel Celeste and Ethereal (Iseria) Queen are in the game as well if you consider the VP characters, though they originate in Star Ocean 2.

Freya is also in SO3, in the dragon's lair after you get the orb from Ethereal Queen. She's the toughest boss in the game.

In Radiata Stories, after you complete the game, in the extra dungeon, you fight Lenneth Valkyrie about half way through. After you beat her, she mentions Lezard, and joins your Friends List.

The next fight after Valkyrie is the one and only Lezard Valeth. Sporting spells from VP, such as Fire Lance, Poison Blow, Dark Savior, and Prismic (Prismatic) Missle. He holds true to his character. Gabriel Celeste and Ethereal Queen are here as well.
