Yup, good point. I might have missed that. Thanks.

Should be. When routing, the narrowest match is supposed to be found first, so it should work. Give it a try and we'll see.
As far as I can tell it works.
There is a route 44.161.0.0/16 for LX, but I have been experimenting with longer (more specific) prefixes (44.161.229.0/25, 44.161.202.0/24, 44.161.203.0/24) and it works fine (so far) within the IPIP mesh.
The only thing you might need to test is connectivity from the network with the shorter prefix towards the network with the longer prefix.
The gateway with the covering (shorter) prefix might be configured to handle this traffic locally instead of forwarding it via the IPIP mesh or a direct interconnect or ...
You may also want to handle the occasional packet arriving at the wrong gateway and forward it to the other gateway.
