Tile over tile embedded in thinset over concrete subfloor

I live in a condo building built in the 70's, bathroom was tiled with 1x1 squares in thinset or some kind of mortar. It is ridiculously hard to take off. The subfloor is sound and the tiles are good and level. Can I put thinset over this tile and then some cement board over that? Followed by thinset and tile?

Or can I pour self leveling cement followed by tile+thinset?

What's the right way of going about this?

That's all that's necessary in this case. Pretty simple and inexpensive actually. Usually a belt sander with 60 (or less) grit sand paper will cause a sufficient amount of ruin to a glazed tiles surface. Aluminum Oxide paper is readily available but Silicon Carbide is better to use if you can find it.

The modified thinset will "grab" just fine.
