Instead of changing the coils for new standard ones, get extended ones. These may have to be made specially though. I'm not very familiar with wheelchair conversions, but I'd imagine it would require a fair bit of fabrication which, along with the weight of a wheelchair user (especially if quite near the rear of the vehicle) would cause some sagging at the rear. So you may be able to get away with simply getting heavy duty versions of the standard rear coils and dampers. I'm assuming your Kangoo is based on the car version, so maybe the parts for the van is designed to cope with more weight.

Another option would be to change the standard rear tyres for ones which are taller. Not sure what size tyres the Kangoo takes, but I've had a couple of similar sized vans which both used 195/65x15. Using that as an example, changing those tyres to 195/75x15 would give an extra 20mm of sidewall height (the distance from the outer edge of the wheel to the outer edge of the tyre).

Couple of things to bear in mind though, any "modifications" such as non standard coils or tyres, you'd best inform your insurer to keep yourself right. Also, raising the rear of the car will also make the ramp angle steeper (though not necessarily by much depending on the length of ramp) which in turn may make it harder to get a wheelchair user into the back.
