    Yes I've done that before/ it works pretty good for 10MHz and up.
    The 02 skymaster that I flew in air shows actually had one mounted right above the pilot's position on top of the cockpit/ it was used on all the Military 02s as standard 20 MHz and up to 70Mhz no tuning needed. I can't remember the military model number/ but it could easily be install and approved.
    If using the long wire NDB/ADF antenna any antenna tuner would work, I have used manual tuners and auto tuners. On my Skymasters 337/p337s and use on many other highwing aircraft over the years/ it is about 20 foot or longer and works good for 5 MHz and up.

    I found this old photo of the 6 foot Military whip/ on a roof/cabin mount for the military 02 Skymaster
    The cabin was reinforced inside with a metal plate under the aluminium.
    Definitely not for speeds over a 175 mile an hour.

    But I have used NDB/ADF long wire antennas even on big KingAirs.
    There is also a standard HF long wire antenna very similar to the NDB/ADF but specifically designed for HF If your seeking approval Google you will find them. Most of them are coated with a black outer jacket to shed ice.

    That vernier throttle is a real bad idea.
