For a single split like a SS, with similar splitting capability, I suspect it would be hard to do with a electric/hyd setup. Big motor, big pump, big cost. I spent about 5 sec thinking about it and think its possible if someone really wants one. When you throw in multiple splits per stroke, is where it could be more feasible to produce a electric/hyd splitter that could compete with a electric/kinetic splitter. Either way, a electric power splitter of any kind is going to be a site specific operation, meaning, if electricity isnt available, you wont be using the machine to split any wood.
Many people like their SS splitters, and just as many like their hyd splitters. Different needs for different folks, I dont need a elect/over anything type of splitter, it wont work where I split wood. Now a gas over kinetic, I could find very useful, but I already have the hyd splitter and I only split enough wood for my needs, so unless a kinetic splitter falls off someones truck in my drive way, I aint likely to own one any time soon.
