I this correct?:
0.0.0.0-[Router_xy-192.168.1.254]-LAN_A(192.168.1.0/24)-[192.168.1.1-mono_A-
10.0.0.1]-[10.10.0.2-mono_B-192.168.2.1]-LAN_B(192.168.2.0/24)

If it is so:
1.Router_xy gets route destinaton 192.168.2.0/24 to 192.168.1.1
- maybe also destinaton 10.10.0.0/30
2. mono_A gets changed:
192.168.1.1 to WAN
10.0.0.1 to LAN
route on mono_A 192.168.2.0/32 to mono-B (10.0.0.2), GW on mono_A is 
router-xy
3. mono-B is ok, but route 192.168.1.0/32 to 10.0.0.1 (mono_A)

4. increase 10.0.0.0/30 to 10.0.0.0/24
5. untag "Block private networks" on both monos
6. i think, but i don´t realy know, then you need 1:1 NAT on both monos.

This should work, but if you don´t need realy firewalling, take a look 
on freesco, it should work easier for you.
