Choose a grid for the finished design?

Question

Design

There is a ready-made layout, you need to choose a grid and develop adaptive versions. How to choose a mesh with minimal design changes?

Answer 1

No way. If the design isn't on a grid, you won't be able to just overlay the grid. Everything will be bad.
Or redo the entire design for the grid. Or just make an adaptive without a grid

Answer 2

adaptive versions can be done without a grid
