You'd need custom built hubs that would need to be able to take a standard fork arrangement, plus the single sided fork of the trike, plus not interfere with the current drive system. If you can engineer one of those then alls well and good but you get to the point where you're overengineering something and may as well buy something that is alredy available on the market because it will end up costing the same.
Not sure how much better you can make a hub that functions well and is designed to stand up to bending moment that would also be affecting your drive system.
