If I understand correctly, you'll have to do a q-in-q tunnel to do what you want.
On the 1100, create 5 vlan interfaces on the trunk interface facing the wireless bridge-
/interface vlan
add name=wan1vlan interface=ether6 vlan-id=10
add name=wan2vlan interface=ether6 vlan-id=20
add name=wan3vlan interface=ether6 vlan-id=30
add name=wan4vlan interface=ether6 vlan-id=40
add name=wan5vlan interface=ether6 vlan-id=50
and create 5 wan bridges:
/interface bridge
add name=wan1bridge
add name=wan2bridge
add name=wan3bridge
add name=wan4bridge
add name=wan5bridge
and connect each physical WAN interface (not the vlan200 interfaces, but the actual physical interfaces themselves) to each bridge:
/interface bridge port
add bridge=wan1bridge interface=ether1
add bridge=wan1bridge interface=wan1vlan
add bridge=wan2bridge interface=ether2
add bridge=wan2bridge interface=wan2vlan
add bridge=wan3bridge interface=ether3
add bridge=wan3bridge interface=wan3vlan
add bridge=wan4bridge interface=ether4
add bridge=wan4bridge interface=wan4vlan
add bridge=wan5bridge interface=ether5
add bridge=wan5bridge interface=wan5vlan
On the CCR, assuming that ether1 is connected to the wireless link -
create the outer-vlan interfaces:
/interface vlan
add name=wan1vlan interface=ether1 vlan-id=10
add name=wan2vlan interface=ether1 vlan-id=20
add name=wan3vlan interface=ether1 vlan-id=30
add name=wan4vlan interface=ether1 vlan-id=40
add name=wan5vlan interface=ether1 vlan-id=50
and then add a vlan200 interface for each WAN vlan:
/interface vlan
add name=isp1 interface=wan1vlan vlan-id=200
add name=isp2 interface=wan2vlan vlan-id=200
add name=isp3 interface=wan3vlan vlan-id=200
add name=isp4 interface=wan4vlan vlan-id=200
add name=isp5 interface=wan5vlan vlan-id=200
At this point, you should be able to assign IPs from the various ISP connections to these final vlan interfaces (isp1 .. isp5) as if the CCR were directly attached to the ISPs.
Honestly, though, I'd probably recommend that you just do internal routing and let the 1100 decide which ISP to map each connection to, but this method should deliver all of your ISP links to the CCR as you want.
