Yes, jack already could do the I/O connections, but jack can't do the
hardware routing, so not only a gain control is missing for what you
want to get. The abilities of audio interfaces are very different. You
seem to have an idea of what does fit good to your personal needs, but
what you want to get seemingly is very unusual. The routing of hardware
monitoring could be much too complex, that's why hdspmixer and/or
mixing consoles are usually used.
