I got 156 bytes following the hello_world_small example.

SOPC builder 7.2 has a serious bug !
if you instantiate an avalon master and click 'generate', the master port is not brought to the outside world. you can not connect to it ! I have a bunch of things that connect to an avalon master port... whoops .... there goes the design. ( DPRAM sits in SOPC builder. the second port comes out through an avalon master port. )

Are you exporting the signals that you want to see at the top-level of your SoPC Builder design?

Many people find SoPC Builder and Nios II highly useful. Wart and "foible" free: No. Useful: Yes.
You might be correct that it won't suit your needs for this particular application, but to write it off completely is being short-sighted, at best.
From what I know (very little) of your application, I'd advise you to:
1. Follow the hello_world_small example for code size reduction.
- Alternately, you could look at the hello_alt_main or hello_led examples, which circumvent the HAL layer entirely, though I wouldn't advise doing it until you really know your way around a Nios II based system.
2. Utilize the Interrupt Vector custom instruction.
3. Look at re-designing your hardware to better suit the way in which Nios II/Avalon function.
Good luck!
