Default [Q] Help to edit .PIT to I8530

Hello everybody!!!

I'm trying to resize the partitions of I8530 (samsung galaxy beam), Android version 4.1.2, JZO54K.i8530XXAMF1.

But I would like to know if what I am thinking is right, before I do.

Well the stock .PIT is that way:

Block Size: 6936576
Block Count: 102400

0x8e0
Block Size: 7038976
Block Count: 8212480

And I guess that could be that way:

My phone currently is in that configs:

(Titanium Backup)
System ROM = 631MB
Internal = 2.11GB
Media = 4.20GB

I wanna let this configs:
System ROM = 835MB
Internal = 2.87GB
Media = 2.82GB

My Questions is below:
1) My phone support this edited .PIT?
2) For the sizes I want the values are OK?
3) If I do anything wrong can brick my phone?
