An A class rig on a uni F16 should be very nice. Two up would perhaps be more load than the mast was designed for. We discussed this some time ago on this forum I believe as part of the "uni vs two-up" performance thread.
Consider "Rocker" C-class who was not faster than the other C-Class boats

That's an excellent docutment Rolf, thanks for posting the link! Pete, skip on down and read all of page 15.
Here's one small part I pulled from there:
She proved very stable in both pitch and roll axes,
leading her crews to have confidence in their ability to
control her. In more breeze, at higher speeds, it proved
important to prevent her from riding too high, as the rudder
elevators, which were not as deep as the daggerboard
wings, could surface and ventilate, whereupon they would
lose lift and settle into the water. This pitched the bows up,
and as the boat continued forward she would then fly the
main foils out of the water, ventilate those, and crash (with
some measure of grace) back to the water surface. It was at
those times we were grateful to have used full-length hulls.
Importantly, we never capsized or pitchpoled the boat.
