Is it smart to stock BG and RES together? Not sure what the pros and cons are. When they cross bread, what is the outcome, do the offspring grow smaller or bigger than either of the parents? Will this hurt my pond in the future? Is it a a bad idea to mix these two?

1 1/4 acre L shaped pond, 6 to 9 ft deep. Finished 7/7/16. Stocked with LMB, HBG, BG, CNBG, RES, FHM. Can't wait to fish it. GO SAINTS!!!
