Yes, Michael, but a-priori. 
Instead, if it is being emulated you could have the instructions
redefined by the software, live, while running. 
You could for example 
-add custom opcodes of your own to the 6502 set
-redefine existing ones (ever wanted to branch far?), or
-define an opcode to do the job of a routine or a whole program, or
-redefine all the opcodes for those of another micro, or
-design a set of opcodes that is best suited for a particular app, or
-etc..
