Yes, I can say from my own experience that some results can be achieved through massage, as well as suction devices and simply wearing a well-fitting bra a lot of the time. I strongly suspect this is how model Andrej Pejic maintains the little bit of cleavage he has, since he and I have similarly slender forms (but that's where the similarity ends!). I managed to keep perky nips and maybe be an AA from a AAA size by simply doing so for a week or two at a time. I've never disciplined myself to stay with it long enough to see just how big things can get this way, but I have found things will all shrink back if you stop for awhile. Somewhere on the web there's a good page on which a non-HRT T-lady explains how she fabricated a gadget using tubing, a hand pump and plastic bowls, but the results after months of use were pretty impressive. She claimed to have gone from zilch up to a C cup. Also, she made nipple enlargers from tennis balls, lining cut holes with silicon caulk.
Constant wearing of a well-fitted and good quality underwire bra with plenty of elastic banding can help arrange things into the right places, too. If you wet the band so it hold the skin tightly, that helps, too. I don't think this will do much to add inches, but it will give you looser tissue in the breast area and contribute to more feminine look.
