Resizing partitions (/system to /data)

I'd like to change the partition sizes of the Moto G. It would ben nice to decrease the /system size as I use CM, and increase the /data size as it is pretty small on the 8GB model.
Is this possible? I searched and read something about the GPT.bin, but couldn't make sense of it..
On my XT1039, there's a partition named "kpan" between system and userdata - no idea what this is for and if moving it breaks anything. It appears to be empty though.
It might be safer to move some rarely updated apps to /system instead of repartitioning.

Change file system of dalvik cache

Hi, I'm new to flashing custom rom. I've accidentally change the file system of my Dalvik Cache to FAT, (the default is ext4). I want to revert it back to ext4 but when I select it, it says invalid partition selection. I haven't flashed a custom rom yet. What should I do next?

AFAIK, dalvik-cache is just a directory present inside /data partition, which is EXT4 formatted (or even F2FS)..
How did you even do that??
There's no separate partition for dalvik-cache.
Maybe you would have changed the file system of /cache partition..
And, to make it clear, /cache partition doesn't hold dalvik-cache.

In TWRP, there's a Wipe option and then I selected Dalvik-cache and mistakenly change the File System to FAT. Now I can't mount it.

Increase system partition size

How can I increase the system partition size? I was trying to install dotOs which has a size of around 4 gbs, whereas the system partition has a size of about 3.5 gb. I've tried wiping, and resizing but doesn't help. Is it even possible?
