I’m planning a walnut credenza build with the side/top joint being a half blind dovetail so the top is face grain all the way across. Is it a bad idea to do 1:6 half blind dovetails to make the carcass? The current plan is to leave about 1/4” lip which would make the dovetails only 1/2” deep on the side.

Should I change up my plan and buy some 5/4 or 6/4 stock for the top? Aesthetically as well as structurally.
