I was actually thinking somthing somewhat different. If the sirius TL's are space/world benders that the Gallic's cannot beleivably reproduce, why can't they just make something that works kind of in the same fashion but with the technology readily available? Say like.. A huge electromagnetic railgun sort of thing with engines/thrusters on each each rail section/part to keep it in a stationary location in the system? Sure it will be more space inefficient and power hungry (solar panels will probly be attached to each section for power), but it will do the same job..
I haven't got the software to make a rough design of what I'm thinking, but I'll put it on my list of "FL things to do" (behind getting planet textures out of another game for Yue).
