This is the one I have. Not sure on your height requirements but it works for me.
Powerbuilt 3 Ton All-in-One Bottle Jack / Jack Stand 11 to 21 in. Range - 640912 https://www.amazon.com/dp/B003ULZGFU/ref=cm_sw_r_cp_api_glt_fabc_F6T2P6932HQ4S8R4DM6M?_encoding=UTF8&psc=1
One of those all-in-one mechanics tool sets with a good variety of sockets, wrenches, pliers, etc. A jack/saddle jackstand combo thingy. Lug wrench. Cordless drill and some bits (especially the 3/4 socket for the stabilizers).
Basically one of these things for the jack: https://smile.amazon.com/Alltrade-640912-Black-All-Bottle/dp/B003ULZGFU
But I also have an Anderson rapid jack, because it seemed like an interesting thing to have.

I have this, it fits behind the rear seat in the crew cab and has a pretty large footprint for use on soggy ground where bottle Jacks sink. The lock is decent too and nice to have more than hydraulics holding the truck up.
Firestone, America’s Tire…I am fortunate to have several Discount Tire locations, and they do 5 tire rotations. It does take time, as you need to make appointments and you wait about an hour to ninety minutes. I do always hit the lugs after 50 miles or so with a torque wrench.
Alternatively, you can buy some stands and a good jack and do it yourself. I have one of these as well as a HF quick jack and it myself if I can’t get a timely appointment.

why 6 ton? I got a 3 ton and i feel its fine for lifting up 1 side or 1 axle.. I havent tried it yet though.
Without being able to see what is resting on what, hard to say.
I own a set of Rhino Ramps and those would be very hard to tip. The only concern is that the surface of the rhino ramp is meant for a tire, while the amount of force from the frame might be a smaller area (the risk that it might punch through the plastic).
So ideally a 12 x12 x 2 wood block between the ramp and frame. However, provided that the frame area is fairly big, and the it's not like your car weighs all that much.
By the way, this product is cool. Too expensive ($300) but cool. They are called Jackpoint Jackstands that let you lift and support car at same point.
These are jack and jackstand in one. Add some pinch-weld adapters and you're all set.

Overall yes and no.
If by "scissor jack" you mean the tire-changing jack that comes with the car, then no, those are not stable or strong enough, ever.
Maybe if you have a pair of wide/stable set of bottle jacks, you could put one on each side and raise one a little, then the other. The tricky part here is that many cars only have one side/front lift point, so there needs to be a place to put the jack stands.
