We should definitely have adjustible-length / procedural landing gear.

Currently the fixed sizes of gear leave you to either have some gear offset deep inside fuselage pieces (which means you can no longer access them, even to get them back out) or have to put landing gear on wings on hardpoints/floating in order to get the correct length, or both. I think this is a perfect instance in which to make use of procedural parts, being able to adjust the strut lengths of the landing gear.

Additionally, the larger gear have very long struts, which I guess is fine for craft like a Dash-8

but looks a bit weird on low-wing aircraft

I think some degree of adjustment in height would be helpful certainly, but I can see this being harder to implement than it appears due to the parts/models themselves. 

Maybe an option to choose say a long, normal and short version with slightly different models could work.  In the same way that we chose different engine mounts in KSP1.

yeah
