Sure, anything is possible. You'll just need to be a millionaire to arrange a convoy with serious desert-prepped vehicles carrying your water, food and fuel... as well as army-level protection for certain areas! That still leaves the problem of not seriously pissing off the relevant governments with such entourage, getting permits & crossing certain borders (repeat:Alg-Morocco is closed)... but yeah, one cannot say, that it is impossible in itself
edit. But crossing east to west somewhere south side of the Sahara, where there are actually some roads, might already change the game a bit.
But I'm just talking outta my #ss on this subject really. Better to check out this link (...and it's fair to say he actually knows what he's talking about):
