You might want to think it out first to see if there's true merit in doing this. This might also be a good time to make any other revisions to the blocks. If you have to 'touch' each one anyway, it's sorta like a "while I'm here..." type a thing.
Also, think of all of the pros and cons. What are the benefits versus negative consequences, if any...
