The 2nd stage needs just needs to be designed to work off the same intermediate (low pressure hose) pressure as the 1st stage is delivering. 8-9 bar is pretty common for intended intermediate pressure for just about anything in the Apeks/Aqualung family. There are some slight differences though, with some 1st stages designed closer to 8 bar and some closer to 9. To make it easy, you probably should just keep the matched set of 1st and 2nd stages, and while you're at it, since you're going long hose you're probably going standardized and DIR, use the exact same primary and secondary 2nd stages so that they are 100% interchangeable in both parts and operation.
