Has anyone switched 3/4 passengers from your room to a new one after final payment?

I found a great deal on a cruise and will be travelling with my 2 teens. We normally book 2 rooms. I normally book a suite and an inside room. The cost of the inside rooms are high right now (cheaper to put them in the suite with us) so I was going book them in the suite.

 

 

I realize that inside rooms tend to go down after final payment. Has anyone ever been able to switch the 3/4 passenger off of an existing reservations after final payment to a room by themselves?

 

I know I can get price reductions if the rooms go down until final payment, but my TA charges 25.00 for price reductions.
