Just remember OSPF does not detect packet loss, and does not properly switch
to backup channels or switches to frequently between channels on marginal
links. So when you use two spectrum channels for 1 link, you double your
chance that the link will get interference and degration.
Going two 10mhz channels, however, reduces the risk equivellent to one 20
mhz channel.

I've heard of some folks using an OSPF router on both ends and two hdx
backhaul radios to simulate FDD, with excellent results. Added benefit of
having a backup link already in place if one radio fails. I will be
trying this on my next set of backhaul deployments.
I have done this. All you need is 2 radio links with ethernet ports, a
couple of Mikrotik (preferred) boxes and a few minutes beyond getting the
links up and running. A 100Mbps HDX link becomes a 100Mbps FDX link for
just a little more than twice the price of the HDX link. The nice thing
is, you can add more links and you have the ability to add even more
bandwidth. Depending on whether you what you use for the radio links, you
can do this very inexpensively.
