This makes 100% sense to me! The shaft collars are a major answer to my question! Thank you so much!!
I looked at shaft collars and there's several types. What should I use?
this doesn't look like a diy project. the construction is superb. my projects are not this nice.I plan on adding a posi diff to StreetFighter, but not sure exactly how to go about it as it will be motor free. I have an image, just need help implementing it. Thanks

Fat tyres and wheels weigh a lot extra over and above regular sized wheels.
Two wheels at almost opposite ends of the lard spectrum but both nominally 20" wheels although you'd hardly believe that from their size difference. A pair of the fatties with 203mm rotors and 20mm axles cripples the scales at a hefty 9.24kg. A pair of the skinnies with lightweight road tyres, lightweight 160mm rotors and 12mm axles floats away at 2.7kg.
You'll be adding at least 10kg over and above a regular sized set of 20" and more if using 26" on all corners. Entirely your choice if you are prepared to move that extra 10kg+. You're already adding that 4th wheel over a trike and already adding a diff. You'll need to be adding a motor to move it with fatties on I would suggest.
I personally like the split shaft collarsThis makes 100% sense to me! The shaft collars are a major answer to my question! Thank you so much!!

So I'm going to throw out another idea that I know works, but would require some custom parts. It is a functioning freewheel diff/limited slip on my Rhoades car. I took pictures because it's so simple and might make some of you whom do machining and CNC work some ideas. So the drum slides over the freewheel and the two post inside the drum fit over the freewheel and engage with it, so when pedaling it drives the wheels, but since the hubs are on bearings and the only contact is the freewheel gear, it will spin freely. If you look at the frame there is a disk brake caliper mounting spot, so I'm guessing this could be used to have disks instead of the band brakes I have on there now. All of the hubs are the same on this bike, front and rear and I have seen them for under $20 a piece with bearings. The axle is a one piece all the way across with a freewheel cassette (actually two in this case) driving the axle from the crank, hope this gets some ideas going.
Hey Brad, if you're reading this and you want to use this idea as add on plans, I can take some more detailed pictures if you want for the Kyoto Cruiser as the Rhoades has 4 wheels instead of three, but has the same type seating and crank setup.
