Yes you can. This is referring to the Family Organizer so you are the "family member":
"If a family member is already paying for their own iCloud+ plan, they can choose to switch to your plan or keep their own and still remain part of the family. When they switch to the shared family plan, they get a refund for the remainder of their personal plan. They can't keep their current plan and use the shared family plan at the same time." from Share iCloud+ with your family - Apple Support
The only proviso I can think of is if you also have a 2TB plan and it is nearly full. Then your joining might not leave enough room for everybody.
