I ended up making all the RGB images Adobe RGB (relative intent)
Any conversion between RGB working spaces (RGB to RGB) only uses the Relative Colorimetric intent, since they are matrix-based profiles (as distinguished from profiles that are based on Look Up Tables - LUTs - which, in turn, support all intents).
The only RGB working space that I know of which uses LUTs is PhotoGamut RGB ( <http://photogamut.org/E_ICC_profile.html> ) -- otherwise AdobeRGB, ProPhoto RGB, ColorMatch RGB, sRGB and all standard RGB working spaces are matrix-based, and because of that are restricted to using just the Relative Colorimetric intent.
