Bridge replacement for Samick PJ 5 string bass

Hi! I have bought a Samick bass 2 months ago. Good tone, smooth at playing and fits very good for a small hands guy like me hahaha.

I was thinking about getting a new bridge cause' the actual one is quite old and rusty. The thing is that i don't really know which buy, I was looking for a Omega Bass bridge, but i'm afraid that part of the bridge can be out of the body, same with a hipshot kickass . What do you say guys? I need options about which bridge can I buy

 

I'm thinking about that too... But, there's a way to change the bridge tone/color? To make a kinda gold-ish or brass-ish finish? Like when you change wood's tone.

Also i want to buy an wilkinson bridge, take off the brass saddles and put it on the samick bridge plate
