I don't believe so (unless you count a very, very brief shot of the full-sized raider prop getting brain surgery in an early season 4 ep. And if you count that as evidence, you may as well say it was a separate design the whole time, considering how different it was from the original CG version). And since the retconned raider was seen in several miniseries-era flashbacks (starting with it's debut), it seems like a tough case to make that it's an upgrade.
Of course, I seem to be in the minority here. The only pre-retcon design I like better than it's successor is the Viper Mark VII. Well, and I preferred the retconned centurions when they still had their giant claws, before they got their comically small humanoid hands for the last couple episodes.
