Perhaps, if the general concept was attractive and could be supported at all, the data of what ASes claim to be at what IXes is something that could be pulled from PeeringDB when they finish their v2 rewrite; it includes an API so might be easy enough to make an educated guess if an AS is present at an IX (and therefore likely to have an IX-run mirror nearby) - care would have to be taken with some of the larger access networks though that we don't end up with the situation where an IX connected mirror thousands of miles from the user is selected over a nearer one that is still likely to perform better even if it is only visible over transit.
