Absolutely you can use a Clark with a Benedini. Because the Clark board is fully functional even without starting the Clark engine sound, the Benedini engine sounds can be easily used instead.

The nice thing is that you don't really need to worry about the specific Clark board, as the Benedini can supply the tank specific engine sounds. So instead of waiting for a LEO or an Abrams, you can use the Benedini files that are all available right now. Pick a Clark board with a decent cannon and turret rotation sound as a stock base, and then customize the engines sounds to your liking.
