If the DLSW+ peer for R1 is R3, then this might work. But you're going to have
 to use R3's serial interface for the peer's IP address. Otherwise, R1 won't k
now where to send it since his default gateway is R2. This would be trivial *
IF* the match clause in policy routing supports 200 level ACLs. Normally, thos
e are not honored unless you are bridging. You might give it a shot to see if
 the "match ip address 2xx" will work or not. Then you can point everyone to R
2, and R2's policy routing will say, anyone needing SNA service should have it'
s next-hop/ip as R1s LAN interface.

Also, is your LAN a TR LAN or an Ethernet LAN?
