Are you saying red photons will excite "blue" color cones? The sensitivity of our color cones do overlap in the midrange colors (eg green), so each cone will be excited by these wavelengths, to varying degrees. I would think, though, that this would not be the case for our blue color cone with the typical red laser. Is there a quantum issue that comes into play that would cause a red photon to register with a blue cone? If so, under these very controlled circumstances, the red light would appear blue.
