Advice on laying vinyl where there are existing tiles tightly stuck to concrete sub floor?

Am planning on replacing ceramic tiles on kitchen floor with some vinyl. The tiles are stuck very tightly to the concrete sub floor. I already took up a loose second layer. At one end someone had attempted removal of first layer of tiles and given up, stuck down a few off cuts to raise the level back up then tiled over with second layer. *Is it essential that bottom layer of tiles is removed, or can they be screeded over and vinyl laid on top? I would prefer to leave them as a) messy/expensive job and b) sub floor is 2 - 3cm lower than with previous level of 2 layers of tiles and would create a trip hazard in doorway amongst other things. *If it's ok to screed over bottom tiles, how deep can the overall layer of screed be? If it could be 5 - 8 cm (depending on thickness of my chosen vinyl) i could retain the existing level of units/skirting/doorway which would be good. I am having great difficulty getting any interest in this work as things are at present. Any advice would be much appreciated, thank you
