ex4300 VC - can I have two layer 3 interfaces on the same subnet

Hi. 

I've two circuits from the same VPLS network connected to two ports on a ex4300 VC, both interfaces are layer3 interfaces, but they need to be on the same subnet. 

ge-0/0/1

set unit 0 family inet address 10.50.20.1/27 

ge-1/0/1

set unit 0 family inet address 10.50.20.2/27 

I want to run eBGP to each one of these IPs through the VPLS network, so if one circuit dies the other one will take over the traffic. So for example ,site A will have two peerings with to the VC switch, one to 10.50.20.1 and one to 10.50.20.2

Is this possible ?

From a config point of view the switch thinks this is fine but I can't actually test it until I'm on site so I would appreciate your thoughts

I am open to any other suggestions,  please note I can not change the IP subnet for the VPLS as it would require changing multiple sites which is not possible for this maintenance window



Thanks
