Need help by more experienced people than me please.

I'm currently running v. 1.9.0 of full wallet, with GB, GBB and CK1 tokens in it , and I would like to switch to light version of it but am not sure how to do it correctly; I'm planning to take following steps :
 - make a full backup
 - unistall full wallet
 - install light wallet
 - restore from full backup

Here are the questions:

1) Are above steps correct and doable? I mean can you restore a light wallet from a full wallet backup?

In case of a positive answer to Q. 1) then:

2) Will I recover either GB GBB and CK1?
3) Will I have same receveing address and therefore won't have to link again BTC I already linked to my current address or what?

4) Would I better follow another route like: installing lite wallet into a temporary PC => send everything from main PC to temporary one => unistalling full wallet an installing lite wallet on main PC => sanding back everything from temporary pc to main PC?

Thanks in advance for your understanding and cooperation.
