Not only a waste, but probably not the best for them.
When we acquired Dauntless it had two 8D's to start and house, the other two 8D's to House, with a Perko switch to combine.
I made one house bank of Four 8D's and bought one Grp 31 for start. Works great and I can still use the Perko if need be.
