There is something that is right now muktzeh and assur b’tiltul. In a number of hours though it will become on it’s own a graf shel re’i. Is there any heter to move it now since l’maseh it will become a graf shel re’i and will then be mutar b’tiltul?
Because right now, this is not a graf shel re’i, there does not appear to be a heter to move it now.
Chazal permit moving a graf shel re’i — see Chazon Ish 48:10 who explains that a graf shel re’i becomes a keli she-melachto heiter (though others possibly dispute this, and give a different definition) — because of the disturbance it causes to the people in its vicinity, and if it is not disturbing at the moment, there would not be a heter to move it.
A possible proof to this is the halachah of not making a graf shel re’i lechatchilah, where it seems clear that until the graf shel re’i is fully extant, there will not be permission to move it.
