It could be done. I'm not sure of the merits. I would guess that it could create confusion based on what seeds are currently used for.
In terms of addresses, I look at about 5 characters after the bc1, the last few, and identify patterns in between. Due to checksums, and the massive amount of randomness of an address, it's unlikely to find 3 or more matching segments in two different addresses you encounter.
