It is possible of course. But it would need to triple the lifespan of Voyager without the expectation that it was going to need to. Fusion and EMP shielding help quite a bit, but I would still put the chances of nothing going wrong during that time at below 50%. Perhaps much lower.
If you have three satellites you do get a better chance of something surviving.
