It turns out that we can put the source map comment into evaled code and devtools do recognize it. This should not present in the final build, so I think the resulting code should be made obvious that the source map is in use, like this:
eval(Function(/* compressed data here */)(...)+'\n//# sourceMappingUrl=foo.js.map')
We would have to preserve the existing sourceMappingUrl comment and update it (and also sourceURL) if the JS preprocessing is in use.
