That is not really much more than the 8080 code Ting distributed.  That 
code includes RAM, UART, GPIO and of course the processor.  Your 1802 
list includes a timer the Ting 8080 code doesn't include.

The size part required by each of these processors depends on how the 
code is written.  I'd be willing to bet the LUT requirements can be 
reduced by a little attention to detail in writing the code.  I seldom 
start writing the code until I have picked an architecture to implement. 
  For example, the 8080 has a number of 8 bit registers which can be 
implemented by distributed RAM rather than separate registers.  This 
eliminates a lot of multiplexers that otherwise have to be implemented 
in the FPGA fabric.  The 8080 has multiple clock cycles per instruction 
time, so it would be easy to implement with distributed RAM if a bit of 
thought is given.

Same is potentially true of the 1802 code.
