Are Gsxr starter’s Interchangeable?

So today my 06 gsxr 1000 starter motor went out I ended up testing all the electric parts and switches and found after about 10 hrs my starter was not spinning or working at all.So was wonder if 600 or 750 starters are the same as the 1000 starter if anyone know or has done this before I don’t wanna spend a bit load of money on a starter and I need my bike for commuting thx
