[HBR] Function Versus Form?

The HBR projects that I have seen scream a faithful adherence to the
original look, as well as function. After forays into a BC-348 and a
seriously dysfunctional Tektronix 310. The Tek 310 was one of those famous
'worked last time I plugged it in,' even though there is *no* way the power
supply, vertical amplifiers, input network (including one carbonized and
opened resistor), and HV circuitry all happened to fail between the previous
owner's last plug-in and my first. I really enjoyed getting the BC-348
going, but I still wanted a receiver that I built with my own hands.
Anyway, back to the point and the topic of the newsgroup.
1) 6V6/6AQ5 final audio. Are these really used that often? I tend to use
headphones almost exclusively, so I'm tempted to leave a beefier,
speaker-ready amplifier as an outboard project. Thoughts?
2) Keeping it all in one box? One problem I have is that I just don't have
a suitable box to house the full receiver. I have two that are way too big
and a few that are smaller. I'm tempted to keep the lower IF and headphone
audio in one box, the higher IF, VFO, and input in another box, and an
umph-y audio with speaker in another. Although this would consume metal,
the modules should have improved isolation, right?
3) AM detector. How may of you use yours? I have no AM gear, and have
felt more of a pull to stick with CW than to branch out. Maybe an HBR-8 or
HBR-11 style would be better.
Thanks.
