2x10 subfloor question

I'm redoing the kitchen floor in my 1970s split-level and was hoping to go with electric radiant (either the DITRA-HEAT or the DCM Pro Fast Fit systems) under tile. The kitchen dimensions are roughly 11.5' x 13'. I'm trying to have the kitchen floor be the same height as the dining room adjacent to it and a hallway. Both of these floors are 3/4" oak laid on top of the subfloor. The main problem I have is that the subfloor in both the kitchen and dining room (maybe the whole house) consists of 2 x 10's laid flat and spaced maybe 1/8" apart.

Given my height requirement, I am hoping to avoid a layer of plywood on top of the 2 x 10 planks (or at least minimize the height of this). I contacted a carpenter very familiar with both these radiant heat systems and he says I should be fine with just a layer of 1/4" plywood or luan. If the 1/4" ply won't work, any suggestions on what options I have with electric radiant heat and tile that would meet my height requirements?
