Is there any particular reason to reinvent the wheel and not to use tool table and tool [length] offsets in X, Y and/or Z? Because that is why there is G43 command and that is exactly why there are dedicated cells in tool table to specify these offsets. That way you can change the tool with M6 and apply tool offsets with G43 (including its location offset along X, Y and Z).
