I am thinking something like this. With the centre section blocked off the air will flow around through the element.
The motor mount in the middle is some sort of plastic. Will it survive in an enclosed heater?

As long as your inlet and outlet are dead-on center it might work fine. If not, you might get more flow around one side versus the other which would cause uneven exchange and hot spots. My own preference would be to have the air flow across the element face as it does as a space heater which would better guarantee even exchange.
Unless the plastic you're referring to is good up to oven temps I would get rid of the plastic. Even with that area blocked off, it's going to get toasty in the middle.
