Maybe. Sowing confusion about the whereabouts of your warheads can be useful, and that was extensively considered.
See for example https://www.princeton.edu/~ota/disk3/1981/8116/811604.pdf, discussing the never implemented “multiple protective shelters” concept.
That even discusses how that can be done when treaties require inspections to be able to count your missiles.
