Update Home Theater with Klipsch RF / RS 3 ii Speakers

[Shep007]

Hi - looking for some advice on upgrading my home theater.

 

After 15 years, I am upgrading my Home Theater. By upgrading, I mean moving to a 4k Projector and updating to a 4k Receiver, possibly moving to a Dolby Atmos system.  However I would really like to reuse my Klipsch Reference 3 speakers because I think they still sound great!

 

In 2002 I purchase a 6.1 system which had a Rear Center Surround Channel... as you can all see... that did not really take off.  So I have my 2 RF-3 ii Towers, 3 RS-3 ii Surrounds and a SW.

 

Can I integrate these into a new 7.2 system and/or Atmos system and what additional speakers do I need that would fit well with my existing system?

 

Thanks for the help!
