Please explain. If I understand correctly, then you can use costumes, or you can use a script something like this

When gf clicked
Do [stuff v]
Broadcast [go v]
Stop script

When I receive [go v]
Hide
Forever
Go to [swapping sprite 1 v]
Wait until < (time to stop) = [now] >
show
Broadcast [swap v]
Stop script

When I receive [swap v]
Do needed stuff

Script 1 is for the first sprite, scripts 2 & 3 are for the second one.
Edit as nessasary to fit your project.
