not receiving OSPF external routes

Aoi
Level 1
Level 1

Hi
Could someone please help me solve a problem with an OSPF router that is receiving external routes(O E2) on different interfafces?

There are 4 routers in the lab.
R1 has two interfaces each connected to a different router (R2 and R3).
R2 and R3 are both connected to R4 each using a differnet interface.

  |----R2----|
R1                R4
  |----R3----|

Here, R1 is running only OSPF, and R2 and R3 are running OSPF and RIP. They all belong to the area 0. R4 is only running RIP and advertising its prefixes.
R2 and R3 are both redistributing OSPF to RIP, and RIP to OSPF.

My question is, would R1 be able to receive two routes with the same destination of R4 when all AD and metrics are equal? In other words, would it be possible to load balance on R1? 
The project I am working on just doesn't seem to work like that. It only keeps a single route (R1--R2--R4 or R1--R3--R4).

Sorry but i won't be able to share the configs for this.
Thank you.

in addition to @paul driver 

I was thinking when you redistribute each other as per your diagram (there will be a loop right ?)
