A solution (there is in fact multiple ways to go about it) would perhaps be
the following:
SELECT in.*, strength FROM (SELECT outE("E") FROM FOO)
What this does is that it first selects the edge and then selects anything
of interest. By doing this you follow the path as it is saved in the
database and the performance should be rather good.
Note that I start from the id FOO. This is also a performance improvement,
instead of first finding FOO and then traverse we start from FOO
straightaway.
This does not however return the data as you want, it will be returned as
one single non-nested json. But that shouldn't be a problem for you to
handle I believe.
