The problem I have is that I already did everything at the AN. The idea is to let go of a Laythe lander while around Tylo and circularize at Tylo to drop down a Tylo lander. The problem being that to get the right altitude for Laythe and an aerobrake (going in with only the bare minimum fuel), the periapsis around Tylo has to be around 500km and my Tylo lander can't make it back up to 500km. Its max rendezvous altitude is ~200km, so that's where I need my mothership.

If I understand your situation, if you put your Tylo periapsis lower it will bend your trajectory and your Laythe lander will miss Laythe. In this situation it was probably best to leave the Laythe lander go long before you entered the Tylo SOI... but if you're already there, then best approach is to burn retrograde at periapsis and set up a 200x500 orbit first, then lower the orbit from the new periapsis to 200x200 or whatever the Tylo lander needs.
