Why don’t you combine a high lift and a weaker lightener? As said above, it’ll be hard to get to a clean level 8 with high lift, but then it depends on your desired tone! I’d blend sections of a lightened with 10vol with HLT (maybe a 12/81 to cancel some warmth) with 40vol, so different pieces have different dimension, and use the lightener around the front for the beautiful “money piece” effect that clients love with balayage!
