My son is 6'5" tall and 15 stone, he dreamt of driving my mog but at the time it was a plus 8 and the insurers wouldn't cover anyone under 30, when I traded the car 18months ago for a plus 4 he was delighted, his sister has driven it, but when it came to it he couldn't fit in, too tall, and I assume this would be the same for a three wheeler. I drove one and even at only 6'1" 17 stones and size ten shoes found it very tight. Don't think you'll fit but good luck finding a car. Perhaps you could have the seat runners moved rear wards.
