Always wanted one of these. Alas, they don't come available very often, and I think my amp-buying days are over an any event....
I think I understand what you want to achieve. You want to use your Space Echo to drive the two speakers independently (in stereo). Is that correct? I think it should be achievable.
Looking at the schematic, the tremolo only seems to drive what I will call the "left" speaker. So that is a consideration. The left speaker drives the reverb tank, and that feeds the "right" phase inverter. The wet signal also gets to the left side, although through a couple of resistors. So, the tremolo affects the left, and the "echo" affects the right. Wet reverb signal will include any tremolo.
There is a switch (no idea what it is labeled, probably "stereo" or something) that controls the flow of the signal from the left channel (either to the right PI or left). Both of these pathways include interactions between the two sides, though. Not quite sure what that will sound like, so you will just have to try it and report back.
It looks to me like the left signal could be completely isolated from the right signal by removing the resistor between the cap at the top of the right tone control and the switch. It's an easily reversible mod. The switch would then give you stereo in that both sides would be independently driven, or blended (but only on the right side; left side would be silent and there would thus be no reverb or tremolo). In "stereo" mode, the left signal would still bleed to the right side through the echo unit, but that would be the only connection. Maybe that would work for you?
That said, I'm thinking you might be happy with it as is.
