Yes and no.
With canister gas and high output WG or Kero stoves, yes, it makes sense. The process would result in more even heating of the ti, regardless of the thinness or gauge of the material.
With low output stoves, some alchy, some WG, turning a canister stove down very low and esbits, probably not. You are already recovering all the heat possible from the heat source using other means, more'n likely. Wind screens/heat screen, perfect distance from heat source, correct diameter of pan for the burner, etc. Then no, it wouldn't help a bit.
As I wrote somewhere else, all that stuff, heat exchangers included, rely on excess heat being recovered and used. If you do not have excess heat, why bother trying to recover it? The logic doesn't make sense, 'ya know? This is generally a product of heavy weight campers trying to "flashboil" a quart of water in 3 miuntes by putting out 10000BTU of heat. Chances are, over half will be *excess* heat and wasted. The spray technology makes good sense even if it only saves a little.
The logical fallicy that I see is the assumtion that ti is lighter. It is not.
