Steve,
I don't think connecting the two RCXs through power adaptors will work. I'm
not sure the details, but I think the rectifiers in the RCXs will cause
problems.
To get a common ground, I *THINK* you could connect the negative side of the
sensor ports on the RCXs together (using something like your connection).
But, you don't want to connect the posivite side together.
In the end, I don't think it will work. But that shouldn't stop you from
trying it...

| (...) It was only ever really a theoretical project. And then I'd have to come up with a way of connecting possibly nine sensors. If you could control both the positive side and the negative side of the rcx connection you could multiplex 9 outputs (...) (18 years ago, 26-Nov-06, to lugnet.robotics.rcx)

| I've wanted for a while now to utilise the particular characteristics of the 2x2 Lego plate connectors. To that end I've built an all Lego multiplexer. (URL) I'm wondering now will it actually work? The yellow connectors are the positive inputs, the (...) (18 years ago, 26-Nov-06, to lugnet.robotics.rcx, FTX)
