What problem are you trying to solve exactly?
In my experience with Ubiquiti hardware, when you put 2 radios close
together, they tend to interfere even if they are on really disjoint
channels. So it will probably be worse than using a single, larger
More generally, doing multipath on a radio network is difficult, because
1) it's very hard to control intra-path interferences, and
2) as you said, the performance of each path is very variable anyway.
If you are interested, these people are using Multipath TCP (in a rather
complex setup with source routing) to load-balance between multiple
gateways in a community network:
