Panel replacement

[LHD Johnsson]

Hello
I am considering changing the siding on the house,
Vertical without cover strips.
Thinking of having three different widths, adding insulation with 80mm
Is it appropriate to have asvaboard behind the siding before nailing battens 28x70?

What is behind the panel today?

Nail batten 22x45
I plan to remove that and install an 80mm insulation board.
On top of that, 28x70 nail batten
And the idea is if one can then install asvaboard
