Doesn't MRV sell a CDWM 'thingy' that will take two GigE links and combine them onto a single 2.5 gb Lambda? You would still need to eat up to SFP ports on your routers but you would get 2 gbps over the same fiber pairs with EtherChannel bonding.
Note: 'thingy' is a highly technical term and should be used sparingly...
