The Hillson FH.40 was the brainchild of F. Hills and Son (Hillson) during the early 1940s. Hill's idea was to add a detachable second wing to a Hawker Hurricane that would allow it a greater takeoff weight and then would be jettisoned in flight. Hills had somewhat successfully tested the concept on his Hillson Bi-Mono in 1941, but a wing jettison with the FH.40 was never attempted, with the program being scrapped in 1943.

After jettisoning the wing would it be able to maintain an adequate level of lift to maintain the heavier loads?

I think that was the theory. I assume they would only jettison the wing after they'd burned enough fuel to compensate for the loss in lift.

I feel like they didn't think this one through...
A jettison of the wing would likely hit the tail as its configured

"Hills had somewhat successfully tested the concept on his Hillson Bi-Mono in 1941,"
It didn't quite crash?

Probably why the Canadian government didn't put much behind it.
I guess we'll never know...

At higher cruising airspeed, probably.
Cruising airspeed is probably significantly higher than runway takeoff speed, where lift at those lower speeds is critical.
I would be much more concerned about a suddenly un-tethered wing, without any tail, and what it would do during detachment. If not done correctly, or if it comes loose at an inopportune time, it could easily pitch, or otherwise randomly come in contact with the rest of the aircraft and damage it.
The CIA Oxcart program A12 project addendum, project Tagboard equipped some CIA A12 aircraft as M21 specification with the capability to launch a D21 photo reconnaissance drone from the plane's added dorsal fuselage mounting point... (referred to MD-21 in assembled form, Mother and Daughter, with the 21 being a transposition of the 12 in A12.)
A D21 drone deployment caused a fatal accident when the drone struck the tail of the M21.
The fourth and final launch from an M-21 on 30 July ended in disaster. Unlike the three previous launches this one was performed straight and level, not in an outside loop to assist in the separation of the drone from the aircraft. The D-21 suffered engine problems and struck the M-21's tail after separation, leading to the destruction of both aircraft. The two crew ejected and landed at sea. The pilot, Bill Park, survived, but the Launch Control Officer, Ray Torick, drowned.

Later, the D21 drone was re-configured to drop free from the underside wing pylon of a B52 bomber.

One jettison test, no crash. Technically successful, but I'd think you'd want to test that just a few more times before you go slapping extra wings on all your fighters.

Seems like an overly complex and crazy idea. Couldn't they have just bolted on a longer wing?

Could be a way for STOL capability.
