The only real change I would make would be to move the sign of peace to before the Eucharistic Prayer. I remember that Pope Benedict XVI even mentioned this change as one which could be examined. I agree with him that it somewhat chops up the solemnity of the Liturgy of the Eucharist.
Therefore, if you bring your gift to the altar, and there recall that your brother has anything against you, leave your gift there at the altar, go first and be reconciled with your brother, and then come and offer your gift. (Matthew 5:23-24)
This change would correspond somewhat with the literal meaning of the above verse.
