I don't think this idea would work. The pressure involved would be very high. I think a die would be needed on the outside of the whole top tube. If any portion was not surrounded it would bulge out. It probably could be done, but not worth the trouble.
Most dents in the middle of a frame main tube can be massaged out if there is no sharp crease. I used steel tube clamps that fit the tube very closely, split clamps about 4" long. If you centered the clamp on the dent and put the clamps in a vise with just enough pressure to allow the frame to be rotated in the clamp the dent would be worked out. Of course the paint is not going to be liking this, but otherwise it works pretty good.
