In general more mallets are more face balanced therefore traditionally encouraging a SBST stroke yes, but there are a lot of mallets now that give more toe hang so the gating motion is more similar to a normally shafted blade.
As for the practice routine, I'm with @Golfingfanatic, I practice with a blade more than a mallet, and then use my mallet for slow greens and blade for fast ones, but that's more down to headlight and grooved insert vs flat face.
I say game the putter you want to game, then adapt your stroke to fit it. I remember reading the story about how Spieth in his fit would intentionally hit bad putts with what clearly fit him better so that Scotty and Co would give him a 009, because that's what he wanted. It's served him well no?
But what are we talking about, practice?
