Create from 200MHz new frequency 150 MHz with help MMCM or DCM (depend at your fpga) and use this frequency as main.
Create new frequences up to 166 MHz using MMCM or DCM and use FIFO for clock domain syncronization.

You may use a few clock signals in one project, but you need follow some rules of clock domain crossing.
I think it is a good solution run your controller and sdram at 150MHz.
