You will be fine. Just don't run the cores five feet apart. Me personally I like to run my cores and coppers off church boards. They work great. We run 3-4 boards per side of boat. 3,5,7,10 color and a 100,150,200,300 copper on the other. Just don't run a core and copper on sane side of boat at same time. Different sink rates in a turn can hurt you.
