Before I would replace anything, I would ask why? The back will come flat. The blade will hold an edge better. The chip breaker will be stiffer and probably make better contact. All those things said, Do you need a new blade? As Steve pointed out, if you do not need to sharpen during your project and if it cuts well, you probably do not need it. The largest concern is that their blades are 25% thicker than standard blades and for some planes, this may mean that you need to open the mouth a bit with a file. You might not, but you might. Some others can weigh in here I think. In theory, the thicker blade should work better. If I replaced one, I would replace both' the extra cost to replace both is not significant.

I expect that on average, you can simply move the frog back rather than taking a file to the mouth of the plane to open it.
