10-bit linearity should be achieved without much problems if you use bottom plate sampling techniques, which forces the bottom plate of capacitor opened before the top plates does, and thus avoid signal-dependent charge injection errors. Also, in supply-voltage of 3 V, your switches should have quite large overdrive with reasonable input swing, and your switches size can be choosed quite small.
Yes, boostrapped SW can have a some effect to reduce the parasitic cap used in SW, but you must still use bottom plate sampling techniques since your sources of SW still follow the input signals and thus causing distortion. Also, boostrapped SW consumed larger power.
