I am open to going back to what was done in the past in the Church. Problem will come from some Catholics who could put up a stink on the practice of communion on the tonuge.
This is a personal choice that you can practice right now. You may receive on the tongue or in the hand. The Eastern Churches give communion by intinction, thus precluding communion in the hand. At the Easter Vigil Mass, the pope also distributed communion by intinction. Since he is not one to use gestures idly, I believe he was making a statement with those actions. (This will date me but as a child, we only had communion on the tongue :-)
I haven't regretted it one bit.
