Hm... would a laser-guided system like Starstreak be able to pick up a
targeting laser projected by the periscope even when launched some
distance away?

No. Starstreak is a beam-rider (well, for a sophisticated version of
"beam") that really needs the missile to start pretty much on boresight
for the tracker.

A semi-active laser system might be more effective for this role: for
slow MPA and helicopters, something like Hellfire might be modified to
suit. However, slow at periscope depth with a mast up is where you
*don't* want to be against any sort of capable ASW opposition.
