Yes, that's what MPLS is made for today.
In V9.5 on your EX4200 you can use CCC on MPLS (Circuit Cross Connect)
This is a kind of Layer 2 VPN.
Here is the explanation of the configuration:

About the scenario, it seems that we need a MPLS enabled network on all PS switches between the edge switches. Isn't?
Is it possible to connect the L2 VLANs across a L3 network without MPLS?. Is it possible to built something as a point to point L2 connection in a L3 cloud?

Yes you're right
You need an MPLS core network.
If it's not the case you need a CPE provisionned L2 vpn, some kind of L2 tunneling but I don't know how you can acheive this .. I am quite sure you can't with only the EX4200.

For a layer 3 interface you need to configure a RVI-interface and for a l2-connection you just need the define another vlan. Then you define a trunk on the interfaces for the RVI and the L2-vlan on both switches and case closed.
I can send you an example of it if you need it.

set interfaces ge-0/0/0 unit 0 family ethernet-switching port-mode trunk
set interfaces ge-0/0/0 unit 0 family ethernet-switching vlan members vlan100
set interfaces ge-0/0/0 unit 0 family ethernet-switching native-vlan-id 408
set interfaces vlan unit 408 family inet address 172.26.254.57/30
set vlans trunk vlan-id 408 set vlans trunk l3-interface vlan.408
set vlans vlan100 vlan-id 100 set vlans vlan100 interfaces ge-0/0/1.0
set protocols ospf area 0.0.0.0 interface vlan.408 retransmit-interval 1
set protocols ospf area 0.0.0.0 interface vlan.408 hello-interval 1
set protocols ospf area 0.0.0.0 interface vlan.408 dead-interval 4
First 3 rules define a trunk with a RVI (vlan-id 408) and te other vlans that you want to trunk. I think it's best that you use the RVI as native vlan this way you can ping this interface if you connect a PC to that port.
Define the ip-address for the native vlan 408
Define the RVI vlan 408
Define the other vlan vlan100
If you are using ospf as routing-protocol configure the ospf
I hope this give you an overview how to solve your problem
