So my suggestion is to have a Logistics Relay chest. A Logistics relay chest is a reqester chest that you can place in your main base and it will request the missing materials for a remote logistic network. So say a remote mining base needs 10 wall and 4 turrets. Then the Relay chest will request exactly 10 wall and 4 turrents. These will be loaded onto a train and then off loaded into a storage chest in the remote base. This should solve the problem of supplying remote bases. The latency from Demand to Supply would be long, but hopefully not too loong so that the blueprint building times out. Also it would be a neat system to see ticking along.
