I think the Malta paper You are not allowed to view links. Register or Login to view., by Bowern and Gaskell, confirms that this could be a good idea. The authors found that among the cipher methods that create results closer to Voynichese are “manipulations that remove phonemic contrasts (such as voicing, place, or manner)”.
In their conclusions: “Encipherment approaches that merged phonemic contrasts yielded the closest overall results, suggesting that ciphers and writing systems with this property may be a useful target for future research.”
If I understand correctly, removing voicing contrast means that plain-text pairs like t/d p/b k/g are each encoded by a single cipher letter.
