The answer to OPs problem really seems to just be “don’t play in real stars”.
Go ahead and use a randomly generated map. Set the number of systems to be lower to start so you can discover the loops early on, and force the game to create more hidden jump points.. It also has the added benefit, unless it was changed from VB6, of enabling nebulae and black holes. Unless my memory fails me those are only present in random games and make for some interesting terrain.
If you absolutely must have real star names....just slap some real star names on the systems you discover. The actual contents of the systems outside of the star type are completely random anyhow.
