Small diameter transport tires
I am looking to put together a set of transport wheels on 5.5" FF wheels. What is the smallest diameter tire that is possible to put on these wheels? I need to get to an 18" outer diameter. Or, if there is a 16" outside diameter option that would be great.
Any Suggestions?

You might check out scooter tires.
low profile
This made me curious so I went on a google search.
Since you're using FF wheels, maybe a 165/30r13 would work? supposedly 17" diameter.

I'm confused, you want a low profile tire resulting in a 16" outside diameter ?
Surely the belly of the car is on the ground then???

Removing body work is not really an option as I would then have to find a place in trailer for engine cover to set and not be damaged during transport.
Why not just roll and load it on the discs?

I picture it now on a stacker, but yikes, thats tedious. Must be a low height stacker though.

stacker roll on
why not just made a plywood disc wheel to roll a few feet
And wrap/attach an aluminum "U" extrusion like this ( https://www.mcmaster.com/9001K776 ) around it to keep it from splitting.

a little more expensive than plywood, but PVC or ABS plate.
Short transport wheels
Spent a large portion of the day yesterday, with the help of Hammerhead Racing and another member of the Arizona formula car group figuring out how to manage the third car into my gooseneck trailer. The photo below will help shed some light on the subject.
It should be obvious that hauling the car as you see it in the photo is NOT how it will be secured and towed. The car was set on wheels that are 13" diameter to prove that another car can fit behind this one, and that there is head room for the car without removing body panels or roll hoop.
Here is the plan and some information we learned yesterday: Rather than figuring out some way to use these FF wheels, I am just going to get a set of hubs to make transport wheels and find four motorcycle wheel/tires that have an outside diameter of 15". We will weld and make up a set of transport wheels specific to this trailer and this application. The car can not ever roll on these 15" wheels unless it is on the stacker. As mentioned previously, the car would be setting on its belly rather than on 15" wheels if on a flat surface.
We had to do a tire change with the car setting on the stacker for this test. That will also be required to use the 15" transport wheels. There is a plan to build a 'bridge' that spans stacker rails to accommodate the most secure means of jacking car up while it is on the stacker. Changing the tires on car while it is on stacker should not be much more time consuming than jacking car up, and putting transport wheels on while on the asphalt.
I had figured that by rolling the car forward enough to put the front wheels onto the gooseneck area, that basically the whole car weight would be setting on the bed of truck. I purchased a load cell gooseneck trailer hitch to get data from during this process, and the load cell proved me wrong. From 'no car' in trailer, to having the car in 'loaded position' the weight on the hitch went up 500 lbs. So, half of the cars weight is still on the trailer tires.
