Changing a Single Property In Each Vanilla Block

[Techno]

I was wondering if it's at all possible to change the slipperiness value of every vanilla block to the same value. I wish blocks had some sort of setSlipperiness(int newValue) method so I could just loop through all the vanilla blocks and change this property. Is there even a way to do this? I know how to replace a vanilla block, but I'm hoping that there is an alternative method so I do not have to recreate every single vanilla block in the game and replace it with my custom one (what a pain that would be)!

as an update, I was able to access transformers to get access to the slipperiness field for blocks, but I cannot assign to it because it is final. Is there really no way whatsoever to access vanilla block properties??
