(i9500) Increase available user storage space? topic

Hi guys, I'm new to this i9500 development section as my previous
device was galaxy s1 i9000. The i9000 cm 10 or cm 10 based
roms had 2 different partitions which increased available user
storage.
I understand the i9500 user available space is reduced
significantly due to the way it's partitioned so even if I uninstall
bloatware in the/system partition, the available user space will
hardly be affected since it's in the /data partition.
So I wanted to know if the partition is resized or if it can be
resized in cm11 or sammy based roms so as to increase the user storage
space available.
