There is a program called FSEARCH in the CCP4 Suite that will dock EM
maps, SAXS envelopes or what have you into a unit cell.
However, I am not aware of any instances where a novel crystal structure
(~4 A or better and no NCS) was solved this way. It is not for want of
trying! I think the lack of success is not because SAXS envelopes are
"wrong" or anything like that, but rather because phase extension in a
crystal starting from ~50A or so is really really hard to do.
That said, I would be delighted if someone could point me to a
counterexample of my statement.

Hi all
I'm looking for anyone who has had (practical) experience using SAXS
data to phase 4.2 A crystals. Please email me.
