Asymmetric routing and pfsync

[linco]

Many companies have 2 links - 2 ISP.
In my case we have link (link1) with PFsense1 and another link (link2) in another department with Cisco FW.
  link1                                    link2
pfsense1–---- pfsync--        Cisco FW
    |                            \          |
    |                            ---- pfsense2
    |                                        |
router------------------------ router
    |                                        |
clients                                clients
Problems in asymmetric routing - half session goes throw link2 and half goes back throu link1. PFsense drop half connections.
Can we set another Pfsense installation for link2 (pfsense2), for example in transparent/bridge mode, without any rules, but with pfsync, which can synchronize state tables with pfsense1.
And no more dropped connections.
