Overall i'd stick with this cause the client likes it, less work for you right? + you"ll get paid (I hope)
but if you really want to make something nice, (like you probaly usually would do) try to make an excuse,
if he's a noob at graphics and audience reactions, show him a new website layout (with your own style)
and tell him that the old one wasnt working right.. or something..
I used this cheap excuse once, and they chose my layout instead
good luck with the client,
