lift with jacks, then block for safety?

Level with blocks. Jacks under corners for stability and fine adjustment.

those jacks would work for making the bus stabile, I would likely still drive on levelling blocks first and then fine tune with the jacks. You don't need to lift the bus for stability you just have to take up some of the preload in the suspension.
If it were me given you want to have a rooftop patio, I would make up a jack frame for the rear at the very least so you can put the jacks out at the corners. This is what I would have as fixed to the chassis and then make an adaptor for those jacks to go into. You may still need a variety of jacking pads to be able to have good travel and contact.

One thing I did not see touched on - these jacks are intended to be welded onto the frame. Most bus frames are heat treated metal and many have warnings about welding and such. I would *NOT* weld on the frame unless you absolutely know what you are doing.

These are medium duty trailer jacks, which is rated for 10K/12K pounds (lift/support, respectively). Some campers and many gooseneck flatbed type trailers use these.

If it were me, I'd get something similar to the following link. This is the same super-heavy-duty landing gear found under many road trailers and will easily support even the heaviest bus. They do make lower profile versions, and most bolt to the frame, eliminating the need for welding. Shop around, they are commonly and widely available at many road trailer parts places.

As compared to an RV most of our busses have such rigid suspension that we don't really need stabilization. I know coaches sometimes have push button electrically operated jacks that will automatically level! I know I would at least investigate servo controlled jacks if I were trying to do it. Crawling under the bus 4x and wrangling each jack by hand seems like a lot of work.

My buddy has a Monoco Class A with 3 point hydraulic leveling jacks (from the factory). They will lift the entire rig off the ground with no problem. Look at one like the Bigfoot for ideas if you want to build your own.
