Connector pinout question

I'm in the process of defining the pinout for an edge connector that will
carry moderately high speed signals. I'm planning on a
ground-signal-ground pattern.

My question is whether it is better for signal integrity/EMI concerns to
replace some of these grounds with power connections, or rather to group
all the power pins together in an area away from the signals.

All signals on the board will be routed adjacent to ground (not power) planes.

Thanks in advance,

Paul
