Use of second LAN?

I currently have eight worker machines are on two Gbit LANs. Right now,
they are configured:

   10.10.0.0/24 with cloud1=10.10.0.11 ... cloud8=10.10.0.18 ... plus a
small number of other machines
   10.10.10.0/24 with c1=10.10.10.11 ... c8=10.10.10.18 ... on a
dedicated switch all by themselves.

To make use of the full bandwith of both LANs, I had thought of playing
with /etc/hosts files to switch networks for each machine with a higher
address than the host in question. Think of it as one LAN flows only
uphill, the other flows only downhill. So on machine Cloud4, for
example, the hosts file would appear as...

127.0.0.1   localhost localhost.localdomain localhost4
localhost4.localdomain4
::1         localhost localhost.localdomain localhost6
localhost6.localdomain6
10.10.0.8   macpro.hoodel.com macpro
10.10.0.9   mstore.hoodel.com mstore
10.10.0.10  bridge.hoodel.com bridge
10.10.0.11  cloud1.hoodel.com cloud1
10.10.0.12  cloud2.hoodel.com cloud2
10.10.0.13  cloud3.hoodel.com cloud3
10.10.0.14  cloud4.hoodel.com cloud4
10.10.0.15  c5.hoodel.com c5
10.10.0.16  c6.hoodel.com c6
10.10.0.17  c7.hoodel.com c7
10.10.0.18  c8.hoodel.com c8
10.10.10.11 c1.hoodel.com c1
10.10.10.12 c2.hoodel.com c2
10.10.10.13 c3.hoodel.com c3
10.10.10.14 c4.hoodel.com c4
10.10.10.15 cloud5.hoodel.com cloud5
10.10.10.16 cloud6.hoodel.com cloud6
10.10.10.17 cloud7.hoodel.com cloud7
10.10.10.18 cloud8.hoodel.com cloud8

Question: How many services would this approach break?
