Hi and welcome to the world of Steadicam! The Pilot is a great system but it is not upgradable. The reason is that the parts are smaller than the standard of the big rig.
You could upgrade the vest to a Zephyr vest which is more comfortable and change your monitor, but the sled itself is a single block.
May I recommend you to look into attending to a workshop (Tiffen, SOA or any on the right side if the forum) it will allow you to avoid starting with a bad posture and injure your back as well as meeting other operators.
The pilot is a great choice for a first rig and when the time comes, you'll be know what you are looking for in a rig and will be able to make the right session.
In the mean time, fly safe and enjoy.
