Would this spring design work?

I'm designing a part with a spring in it, but have a very thin profile to work with (~0.8mm).

I've calculated that in order to avoid permanent deformation, I need a flat spring that's ~3.5mm wide, but again, I only have 0.8mm of width to work with.

So, could I instead have a few smaller sections of material that are each 0.8mm thick, but add up to 3.5mm?

I drew a quick picture of what I'm thinking above. Is this crazy, or would this work?
