As long as Ego Dissolution and SLR are at the beginning, and Grounding is at the end, the sequence does not really matter. Just add them somewhere in the middle of your stack.
I would highly recommend to replace Ego Dissolution with Vibration of Transcendce (VoT) because it raises vibration and has Ego Dissolution built into it too.
Or add in Vibration of Creation (VoC) as the third one into your stack if you don’t have VoT.
