FH, fratricide is an issue but one easily avoided. The low man can remain above manpad height and the ML SAM is probably neutralised by now. While EO is capable of high resolution at altitude low cloud can negate that thus offering a better eyeball effect.
The Typhoon prefers much higher altitudes than the Tonka.
Certainly it would result in more comms and higher workload except that it would relieve the Typhoon pilot from doing the search and acquire bit - a 3-man or 1.5-man cockpit
and a disclaimer, I am purely speculating and have no direct experience except from the weapons course 30 years ago which went into laser techniques in great detail.
