Our experience is that most routers' UPnP / NAT-PMP implementations don't work well with (our) automated tools. So this would have to be done manually, significantly reducing the pool of available volunteers.

No, the Tor network does not currently eliminate relays with poor bandwidth or poor uptime from the consensus. (As far as I recall.)
Therefore, a BOINC-based, or other widespread project, runs the risk of bloating the consensus with low-uptime, low-bandwidth, or asymmetrical-bandwidth relays.

I don't think we're talking about the same kind of security here.
* configure the relay bandwidth limits and various other options for the context?
* fix the relay when it breaks?
* monitor each virtual server for suspicious activity?
I don't think the average BOINC volunteer has these skills.
That said, a similar project deployed Tor bridges on Amazon EC2 using a preconfigured image. It was discontinued as it was unmaintained.
Why not create a Tor bridge image, which tests for bandwidth and uptime (is this possible?), and then starts Tor once certain basic criteria are satisfied?
The image could then be distributed via Amazon EC2, other VPSs, and maybe even BOINC.
(And if a user has the bandwidth and uptime and skills to run a relay, they can edit the torrc to make it a relay.)
