NO ,you cant or maybe you can
Samsung phones are flashed via Odin
Evn Clockwork mod has to be flashed via Odin
It is somewhere in the recess of internet .
But You will be responsible if you Hard brick the phone
There are no ROMS even if you install clockwork.

Battery wise I would suggest you to stick to 0.433 .
0.564 is a nice ROM .
It has support for Flash 10.1 and Framework is very Good .
It may save you some battery too since it runs a bit cooler .
But it is kernel 2.6.32.42 not the samsung 2.6.32.9 so it may act up on some phones .
But thats a risk with every custom ROM .
I cant actually recommend any ROM to anyone .
It's a personal choice like clothes .
People are divided between 0.433 ,0.533 , 0.564 and Perseus 1.1 .
Each has his own taste and belief .
Only when you install it and run it for more than a day you will know which one to go for .
