star wars - Was Vader's suit prebuilt?

Was Vader already going to be in a suit before he was injured? Many dark side warrior such as Darth Revan, Starkiller, Darth Bane, and other Sith that specialize in close quarter combat wear armor as well. Reading the wookieepedia page on Vader's armor, I notice that his armor most likely used Sith alchemy along with many custom features which probably would take a long time to make. Could it be possible that Vader already planned to use an armored suit as a Sith, but as he didn't plan getting his limbs cut off, Palpatine was forced to rush its completion? Although the suit had some advanced features such as the mandalorian crush gauntlets and as well as audio enhancers and sonic dampeners, a lot of other parts were pretty low tech. Was it possible that the suit was in its prototype stage as purely armor when Vader lost his limbs, then quickly converted with life support systems into its final form.
