In fact I was trying to the same thing using nqpoly4 voice allocation, 
but I wasn't thinking that there's no gain in using it for this kind of 
purpose. In fact the abstraction are all instantiated when the nqpoly4 
object is created and the bang to the abstraction outlet only tells 
nqpoly4 which voice has been freed.

Anyway I've modified your example to make some sounds and I've noticed a 
problem. If I edit my voice abstraction and then I use the nqpoly4 right 
inlet to reset and reload the abstraction, then one of the voice becomes 
silent. I've not understood completely nqpoly4 inner workings but I 
guess this is due to the fact that we make it create one more instances 
(eg. [nqpoly4 9 ... ] with [poly 8].

This problem is solved by using the same number for both [nqpoly4] and 
[poly] and adding a [- 1] between the poly first outlet and pack first 
inlet.

I've attached the patches.

Ciao,
