I think that this is the trickiest part of reverb design: tuning the delays, and knowing how to tune them for a given topology. The allpass loops are fairly forgiving; feedback delay networks / parallel combs less so; FDNs / parallel combs with lots of output taps even less so. Once you start embedding allpasses within FDNs, it gets ridiculous. I spent the first half of the 2000's learning how to create stable structures, and the second half learning how to make those sound good.
As far as papers, if you have a local university, try going there and see if they have subscriptions to the journals in question. I head over to the University of Washington all the time, and email papers to myself.
