Smalltalk <-> Objective-C

How about the idea that instead of translating the Squeak VM from 
Smalltalk to C, that it would be translated to Objective-C?  Wouldn't it
then be easier to write the VM in a a more natural style of Smalltalk?  Is
Objective-C standard enough to make this a feasible idea?
