One person made the bracha and blew some blasts. Then, for some reason, he is physically unable to blow the rest. Can someone else complete the job?
Does it matter if the switch happens in the middle of a group - say a person blows just t'kiah / shevarim but can't do the clsoing t'kiah of the group
vs.
1st person completes 1 set of tki'ah-shevarim-t'kiah but there are 2 more such groups (as in the case of the 1st 40 blasts done before Musaph)
vs.
1st person completed the full set of the 1st 40 before Musaph, and 2nd person completes all the other blasts beginning with the sets done during Musaph repetition?
