No need to re-tune as long as you're within 32MHz (maybe 64MHz due to complex sampling?). Since you have a good amount of bandwidth to work with at the host, you could just "hop" at the host level with your samples and a mixer. Or, if you need more bandwidth, you can put the hopping sequence into the FPGA going into the DUC and go to a different phase accumulation based on how many samples have just been transmitted. Plenty of ways to skin this cat without having to retune as long as you can fit within the DAC bandwidth.
