I think the benefits of having a slab to tie everything together are well worth it. I don't know what the options are for extra thick resilient flooring but I would look into it. I put in a bathroom in my parents house that was on a concrete slab and I first laid down a 1" layer of foam insulation, then a 3/4" layer of AdvanTech subfloor, then 1/4" luan over that, then click together vinyl. I am very pleased with the result as the foam and air trapped between layers seems to provide a decent cushion.
