I would pass on the system. You can always circle back if you get tired of looking for another home. Bear in mind you can create a stable point for a makeshift comm if you find an alpha core. Also, in my experience, being far from the core worlds didn't have a significant negative impact on my colonies. I was at the farthest edge and had a -16% accessibility penalty (later dropped to -10% with other colonies established). That's a 20 or 30 point swing but if the system is ideal I think it's worth it.
There are no guarantees, but I'm sure you will find a better system than this one. The others are not wrong that this will work, but I'm picky and like exploring.
