Using dynamic data for this is not going to work in BGP, so this would have to be static information (hm, packet loss is not too static, hopefully).
Injecting dynamic data into a routing system already strained by the _static_ information is going to kill it. It is as simple as that.
Introducing "metrics" like this like this is not contrary to BGP design philosophy: the way in which an AS selects the best route is not defined in the RFC and the length of the AS path is certainly not the best possible criterion.
Six years ago i wrote a proposal for BGP Path Metrics: http://www.kotovnik.com/~avg/old_page/draft-bgpmetric.ps For some reason it didn't have any effect. --vadim
