passive mixer limitations?

I've read in several sources that fully passive summing suffers from a variety of problems, some that get worse as the number of inputs increases. If a mixer was going to be utilized with a very limited range of inputs, would it be possible to evaluate whether a passive design would be suitable?
Specifically, I need a 4x2 line level mixer. The inputs would ALWAYS be fed by the balanced, line level (+4dB)outputs of mic preamplifiers. The mixer would require only very minimal features: 4 input faders, 4 panpots, 2 summing busses and two output faders.
Short of building the device and testing it, how can I determine if a fully passive design could be successfully implemented in this situation?
If the only significant problem would be signal level loss, that probably wouldn't be a deal-breaker. I have several 2 channel Telefunken line amp modules that are clean enough to restore 10 or 20 dB of level without trashing the signal.
Has anyone put together a passive device for this type of use?
