Yes,

QoS on one segment of an internetwork when the traffic has to traverse 4 segments is vitually the same as no QoS. (depending on your needs)

You'll need IP Precedence on LAN1 to R1; then you'll need to setup LLQ/MQC or CBWFQ from R1 to R2 & R2 to R3 then the final ingress port of the switch on LAN2.

Please see the following link for more info on LLQ/MQC and CBWFQ:
