Hi Kathy, yes it's ok to lay over. But do a test patch in an inconspicuous place to make sure you can get the thinset to adhere to the existing glaze. For instance, go into a closet or pull out the frig or range, rough up the existing tile with a sanding block, spread on some thinset, and slam down a tile. Wait a week and see what it takes to tear it up - you'll have your answer.
And do a walkthru considering the added height - look at everything. For instance, you'll probably need to double up on the toilet waxrings, assuming you don't tile up to the edge of the toilets.
And trimming off the bottoms of doors is no big deal, at least not compared to busting out a house full of floor tile.
Don't know what your situation is in the kitchen, but consider removing and replacing the cabinet toekick trim. Much cleaner look than trying to cut and fit tile up to the edge of the cabs.
Have fun, and remember the safety glasses.
