No.
Bones aren't "closer to Rock." Ground is an thematic typing. Bones are associated with the earth/ground in a variety of ways. In many creation myths, people are frequently built of mud or clay or earth. The maxim "from dust to dust" acknowledges this trope. Belief in an underworld where people go after death is also a common belief. Burying people underground upon death is a practice that can be found all over the world as well. Bones and earth are hopelessly intertwined.

The same logic applies to mud attacks and striking attacks, like Headlong Rush. The type chart is illogical nonsense most of the time anyway. Just embrace it.
