Yes, you can use the BGP local-as feature. I used R3 and R4 as opposed to
R1 and R2.
R3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R3(config)#router bgp 65000
R3(config-router)#no auto
R3(config-router)#neigh 10.10.34.4 remote-as 200
R3(config-router)#neigh 10.10.34.4 local-as 100
R3(config-router)#
termsrv#4
[Resuming connection 4 to r4 ... ]
R4#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R4(config)#router bgp 200
R4(config-router)#no au
R4(config-router)#neigh 10.10.34.3 remote-as 100
R4(config-router)#
