Preparation for tiles

Hi, writing here for the first time. I am renovating the hallway and want to have underfloor heating + tiles. The current floor consists of a concrete slab, 70 mm joists and fiberglass, 25 mm tongue-and-groove wood, thin masonite, and thin laminate. There is an unfinished basement under the slab that stays around 13°C in the winter. I have concluded that it must be cleared down to the concrete and built up to reach the level of the current floor and make space for underfloor heating, tiles, and reinforced self-leveling compound. The question is, am I making a mistake if I cast 50 mm lightweight concrete boards on the concrete floor, followed by a reinforcing mesh, electric heating cables, self-leveling compound, etc.? The idea is that it should insulate a bit against the basement, not weigh too much around 500 kg, and be as cheap as possible?

Thanks for all the tips and ideas.
I'm leaning towards eps insulation for my part.
