Daikon 2 zone A/C -Heat pump ductless sizing

Hey Guys, In sizing two identical rooms for the wall cartridge BTU's, the calculator puts me at just under 7000BTU's for each unit. One of those rooms is a garage bay with a complete wall, obviously, the garage door, which is insulated. The door has windows towards the top all the way across.
2 questions - 1) Should I bump the size of this garage unit to a 9000 BTU ? 2) Can you have a 2 zone system with un balanced wall units, one 7000 BTU and one 9000 BTU,... or must they match ?
I'm located in Long Island ,NY.

Thanks in advance for the input !!!
