Tank shell for mini rc car

I have a mini RC car, one of the cars that are in the little plastic soda can case, and I thought that it would be pretty cool to have a tank shell rather than the original. This is meant to go on top of the car, it doesn't replace the shell.
Here's the RC car, in case you wanted to get one for some reason or other: https://wltoys.co/product/wltoys-mini-coke-can-speed-rc-radio-remote-control-micro-race/
