Edit: Haven't tested it yet, but what happens if you:
MC
CM
M = MFE
C = Cable
It works sort of but seems like it would be unpredictable on a large scale. Using just 2 cables, 2 MFE and 1 generator the MFE that was next to the generator charged but the other didn't. Attaching a redstone circuit to the uncharging MFE made it charge. I hooked a macerator to each MFE and the one I turned on first's MFE drained all the charge from the other MFE.
I might experiment with it later.
Ok, I cheated to do my test and replicated a few MFEs and cable, and enough to make a nuke... but no more!
Now, we can only do a single thickness because of the 3 connection wire deal... but this is how it charged:
B, then C, then D... Now A was slowly filling up from the solar panels, and I technically added that after the Nuke was charging B, so I can't tell if that first one has a huge impact. After A was filled, it stopped filling up MFEs ... I don't know if it was because I flubbed the order or what. One odd thing I noticed is that U (the one all the way at the end) was filling up, 16 EU per tick the whole time.
I put a redstone torch next to one down the line (let's say M) and all the ones further down stopped (as expected) while it filled up with trickle charges. There is a small amount of juice flowing to each one, but it's not consistent. I placed a miner at the end and it slowly putted along as it got it's dose of 16 EU every now and then. Placing a torch by it, letting it fill up a few thousand and breaking the torch made it suck all the juice out and go back to sputters.
It's consistent in that it fills up from the power station side first but it doesn't release it's energy on demand.
