Well, inks effects became crossplatform as of version 2.7.  But regardless,
there is the blendLevel property for images (and any object in v2.7) that
would allow you to make images less opaque (to reveal a darker color
underneath?).  Or start out with semi-transparent icons and make them fully
opaque upon mouseEnter.  I think dynamically affecting the imageData of the
images might be overkill for your situation and perhaps not fast enough.

I would ask first though, do your icons really take up that much memory?
