Your best chance is warranty claiming off a company and using phtoshop to Shop the s/n on it (its not impossible you will have to be in detail about what was on the console to match it

I am aware of the standard S/N method but i was thinking of trying an instore method and using a real item.

I haven't seen a switch serial number and how its displayed but if it's printed on the console no chance if its a sticker you will have to use the exact sticker nintendo uses and if it's in warranty or any other info that's on the sticker

The Nintendo switch was just and example I'm thinking anything that has a serial sticker that i can just swap round and return the broken item with the S/N sticker from the one i bought from them.
