I think I would use this scenarios:
Lo1 - bind to Ge1.100
Lo2 - Bind to Ge2.200
Lo3 - Bind to Vlan100
Lo1
ip address 10.10.10.1/32
Lo2
ip address 20.20.20.1/32
Lo3
ip address 10.10.10.2/32
Lo1 and Lo2 transport + nat dia for vpn 1
Lo3 nat dia for vpn 2 (custom color and policy)
It difficult config, but it because of cisco doesn't fit to use as isp border in controlled mode
