Hey guys, chill.... Take a look at this thread, fun to read;
Grafting Bananas by the Insistent Banana Grower - Mauro
Let's say it can be done, it is probably something in the past when 'naner cultivars were being transported around as a food source. What are you gonna to do if the corm of your latest cultivar is rotting? I think by pre-science/TC era, someone would have thought of grafting it to save a potentially new and valuable food source. People then were very resourceful and did weird things. There in China, people made pliable mats out of ivory, yes, elephants' tusk and now the method is lost in time.
Remember, then, you don't order over the inter net and it is flown to you. Those times, it would have taken many days of walking (Marco Polo?), ship on the crazy high seas to get a replacement. So in the meantime, in all legality, I guess we will have to use the infamous line,
innocent until proven guilty...
