It would be easier to just create a jumptable that directly jumps to the 
appropiate code.
For example:
mov w,opcode
add pc,w
jmp code_opcode0
jmp code_opcode1
etc.

All main entries must then be in the lower half of a single page.
If one page is not enough (most likely) then just do for somee opcodes
code_opcode0:
jmp @code_opcode0_entry
to jump to another page. Return from each code with a retp

You could also double the opcode at the start like this:
mov w,opcode
add w,opcode
add pc,w
jmp @code_opcode0
jmp @code_opcode1
etc.
but I expect this takes more codespace.
