The flight deck is 100 feet wide on the Canberra class and the wing and rotor diameter on the V-22 is 98.9 feet wide, so there isn't a whole lot of room there and very little margin for error on most of the flightdeck.
There might be one or two spots on the flightdeck that can handle the V-22 but I would hazard a guess at "no" for the majority of the ship...
In terms of hangars, elevators etc that wouldn't be a problem as it has a folding rotor capability and it's wingspan and fuselage is much smaller than the Chinook which is intended to be operated from the LHD's.
Does anyone know if the Chinook has to lock it's rotors in the "admin" position before they can be taken below deck on the Canberra Class?
I found these stats for you AD about V22 and chinook, when I was looking for infomation on the LHD crane and lift capacity.

The fl ight deck has been designed to operate, launch,
receive and provide support, both day and night, to planes
and helicopters such as the third Squadron’s AB-212, the
fi fth Squadron’s SH-3D, and the ninth Squadron’s AV-8B
Harrier II Plus. As well as the aircraft in service with the
Navy, the ship is able to receive the Army’s CH-47 Chinook,
Eurocopter Cougar and Tiger as well as the NH-90 when it
enters into service with the Navy and with the Spanish Army.
In a signifi cant qualitative leap, this ship is also designed to
operate with the STOVL version of the JSF, the F-35B Lighting II,
if the Spanish Navy decides to acquire this exceptional plane.
A touchdown point has also been reserved astern of the fl ight
deck that is specially adapted (in dimensions and resistance)
for the special needs of the new V-22 Osprey tilt-rotor aircraft.
For the transfer of aircraft between the hanger and the fl ight
deck, the Juan Carlos I has two elevators, each with a capacity
of 25 tonnes and suffi cient size to be able to carry up to the
new F-35B Lightning II, or a helicopter the size of a Chinook.
The capacity of the hangar is variable depending on the mission
profi le. This means an area of 1,000 m2 would be available
for an amphibious type profi le. This surface area could be
increased by a further 2,046 m2, using the upper garage to
have greater capacity for the aircraft. This means the hangar
would reach 3,000 m2 for an aircraft carrier type profi le. The
hanger itself, situated further astern, can house up to 12
medium-sized helicopters. In the case of the LHD operating as
a temporary aircraft carrier, the vehicles and material would
be substituted by between 10 and 12 STOVL planes, as well
as the dozen helicopters previously mentioned. In order to
provide support for airborne operations, it is estimated that
the ship has suffi cient fuel, spare parts and arms so that the
embarked aircraft could carry out their operations without the
ship needing replenishment for up to a maximum of 50 days.
The planned airborne capacity is for her to transport and
operate up to 30 aircraft including medium-sized and heavy
helicopters in amphibious operation profi les, or between
10 and 12 F35B planes or AV-8B+, plus a similar number of
medium-sized helicopters when acting with an aircraft carrier
mission profi le at times when the Príncipe de Asturias R-11 is
not operational.
