Here is one of my very early lures made more than 10 years ago after a catalog picture .
If my memory serves me right , the original was a "Mann's" lure called "Pogo Shad" , but I haven't seen it since anymore , suppose , that it was quite short lived

.
It still float's up with its tailfin just breaking through the surface , I am sure that the original hangs different or even sinks , never held one in my hands !
I fish it in a jerk-and-pause manner , the offset tail causes it to roll and vibrate at quite a high frequency and it goes down to one foot this way

.
It has a hollow chamber inside the center of body with a BB , but since I lacked experience those days , that rattle chamber is not very loud being furnished of wood exclusively .
It is weighted heavily under its chin to stabilize its running , the cross-section is oval with the belly a little fatter than the back .
It is carved out of one piece of light teakwood , but I think to make the shaping easier , one could also screw a metal tail(homemade of aluminium or a fitting Indiana-blade) onto such a lure to achieve the same action , one can maybe even test and/or alter the action by bending the fin to different angles .
I guess a fin set at approx. 90° or even more(pointing forward) would result into a higher frequenzy of moves , but also render the lure more prone to overturning , thus more counterbalance belly weight would be required . Just a matter of trial and error , I haven't bothered for it , since any kind of vibrating lures have not proved success in my local waters , only caught very few fish on such .
Only utilize their noise pattern frequently to call perch to come investigate below the boat , they then would strike on my wife's rod with a small pirk(jigging spoon) attached , hardly on that crank !
Maybe also make ONLY the belly a bit deeper to be able to carry some more weight , guess , that the tail portion has to remain slender to still provide that distinctive roll and vibration

.
You can determine about its size by the squared background paper , five squares make up for 1" .
Well , you asked for different shapes , this is one , maybe it could help
