Resize system partition in TWRP?

[BewareAlbatross]

Couple of quick questions. I'm wondering whether for a custom CM13 ROM I could resize the system partition since there's a ridiculous amount of free space to play with on this thing and I'd love to see a standard gapps package installable. But:

Will it boot, will it figure out the system partition regardless of the changed blocks?
And will it be possible to ever resize back and go back to stock without the very finicky Kindle firmware griping?

Wondering if anybody knows the answer to either of those. Or both. Thanks!

You could try to adjust the system partition if you really wanted to, but be aware that if you do so, there's a pretty good chance you can cause the Kindle's firmware to have a coronary if you try to return to stock without adjusting the partitions back. My recommendation is to back up everything (including the boot0 block if you haven't done so yet), take note of the original partition sizes, and only modify stuff you're 100% comfortable doing. Make sure you have working ADB and fastboot on your computer, as these will help you out immensely if you need to do emergency recovery. Also make sure that whatever you do, do not touch the boot, recovery, or EFS partitions; those may cause problems if you adjust them at all.
