keel conversion - fixed to lifting

I have charted out 6 sections 1/4 scale. I had charted that one out too, it carries it's thickness a little farther aft, doesn't it. The nose isn't as thick either.

 

Perhaps those characteristics are favorable?

 

I made a full scale template of 0010-34 and it looks mighty thin (maybe structurally?). The 0012-34, would it be a terrible substitute to gain a little more thickness? I made that template and feel a little more secure with that thickness.
???
Thanks
