    Somebody built a Beast on the other forum. He cut the frame to install a China girl.
    I would install a friction engine kit or mid drive electric.

    for a person willing to take time and work carefully, most anything can be done - I've done some heavy stuff like that in the past, but can't really afford the time to do all the custom work these days

    from the pic, it looks like getting the motor in there will be too tight for standard mounts and maybe a lay shaft (or two) will be needed to clear that tire and get back in to the the hub again - jack shafting to the pedal side should work, but seems a shame to waste that on a one speed

    OTOH, I really love to see nicely turned out projects like that
