The jump up from a half sphere seems quite a lot but lets figure out how much.
Half Sphere =
- 6 Pentagons
- 5 hexagons
- 5 half hexagons
The most recent version is
- 15 hexagons
- 11 pentagons
- 4 half hexagons
So 16 parts verses 30 parts is virtually double. Add 6 half spheres and another pentagon for a full sphere.
I wonder if it’s more prudent to ship each ‘full’ sphere with a spare panel of each type for spares. This could be a possible stretch goal since it doesn’t take much in extra effort.
