can you swap different /piston sleeves in different motors if the have the same stroke and bore?

my motor has a stroke of 16.80 and a bore and 16.26, could i take a piston/sleeve set from another motor with these numbers?

the reason i ask is because i have a picco .21b(3 port) and its hard finding parts for this motor and i noticed that all of picco's .21 motors have the same bore and stroke.
