You can't just take a piece of wood and replace it with aluminium. Aluminium is soft as fuck and can't bear repetitive loads. Wood is a directed material, meaning that it can only withstand forces in a specific direction. Aluminium is only slighly directional, depending on the way it was hardened.
Replacing a piece of wood with aluminium would require you to rework the structure around those facts. Your new support structure can suddenly take forces in all directions somewhat equally, but it requires more vibration reduction.
Replacing aluminium with fiber reinforced plastics works the exact opposite way around. Carbon fiber is SUPER directional, meaning that even a few degrees off fiber direction it can only take a tiny fraction of the maximum force along fiber direction. It's even worse than wood in that respect. However most fiber reinforced plastics are very resistant to repetitive forces.
You can easily drive a screw into wood, you can't do that with fiber reinforced plastics, you can easily use bolts to connect aluminium, you can't do that with either wood or reinforced plastics.
Some shapes are completely impossible to produce with reinforced plastics.
All of these different properties have to be taken into account when (re)designing any machine. Picking the material you want to use comes far earlier than deciding on the shape of the part, and far far earlier than deciding which attachment methods you want to use with the other components.
