This is an interesting need. Well, I'll let the "Mother of Invention" run its course here. First, a couple of observations and assumptions....
I assume that the airplanes cannot be modified for display... This may mean they are all tail heavy...
1) A .032 music wire "chassis can be formed, soldered, epoxied to mimic the scale landing gear. Not a tough issue but it will be time consuming with liberal use of patience. Plastruct plastics can be cut and sized to scale size and dimensions for gear doors, etc.
2) Wheels can be fabricated using small aluminum tubes with rubber o-rings for tires. For very small wheels, there's a load of useful bits that can be gleened from a "spent" Bic lighter!! Disect one sometime and you will be shocked with all the small brass valves and tiny o-rings.
3) Here's the dilema- the CG will most likely be aft so how can a "chassis" stay attached to the belly of the airplane?
a) Yes, glue could be used but stick with a high tackifier style like "GOOP" which adheres well but can, in theory be removed without damaging the model.
b) Chances are that the undercart will need to be affixed to the display again, because of the tail heavy scenario. So the placement of the airplanes in the line-up has to be well planned. Leave spaces for the missing models to allow an organized display.
c) As a follow-on to the previous comment, I would suggest setting these models in place as if at the annual EAA "Air Venture" where various types of airplanes are grouped according to size, vintage, usage, etc.
Finally, if the model can be modified, that brings some simplicity but overcoming the natural tail heavy issue will need to be addressed in a like manner.
If I missed anything, let me know. I will be happy to offer solutions.
