Doepfer

It would be interesting to have a little 4" or 5" speaker built into
the portable case...Doepfer doesn't make such a thing, do they?  I'd
imagine it would be very easy to build.  Any DIY'ers ever try this? 
Do you think I would need a powered opamp stage, or is the audio
output strong enough to power a low-wattage speaker on its own?

The headphone amp will power a small set of external speakers...

The module sizes and also the powersupply-voltages are very common for 
industrial modular technologies. I could imagine, there are active 
speaker modules available for non music industrial systems, or e.g. for 
intercoms or for audio distibution systems as used in hotels, 
supermarkets or similar locations. May be this is a hint to search for 
such a module.
