I know you can do an inch or two wwith spacers and more than likely be safe. You can also make hockey puck body lifts work if you drill them out and sleeve it but in the end is it the safest method?
If I am offering a suggestions to someone about modifying their car I am going to suggest something safe and how I would do it.
If you are looking to lift the car 4-5 inches you are not going to be able to do it with just longer springs...
This is all that is needed in order to lift a Suzuki Sidekick 4". I chose this because other than your car not having a driveable rear axle the suspensions are similar and the vehicle weight is similar.

Your average cost for a mass produced 4" suspension lift for a vehicle with independent front suspension is $1000 plus installation. Now that you are looking at a custom one off you could be looking at more for parts due to trial and error and also much more labor.
You could try something like this for 2 inches and could be alright. You have to look at your cv joints and axles to make sure that at the new angle they would not be rubbing on anything.
This would not be my choice but it is your car.
Link to someone who makes them for Suzukis and may be able to make them for your car if you had the diameters needed.
For the amount of lift you are looking for the air ride kit would be a good option.
