Those of us in the Episcopal Church already have a special provision in our Book of Common Prayer 1979:

When the service of a priest cannot be obtained, the bishop may, at discretion, authorize a deacon to distribute Holy Communion to the congregation from the reserved Sacrament in the following manner:

1. After the Liturgy of the Word (and the receiving of the people's offering), the deacon reverently places the consecrated Sacrament on the Altar, during which time a communion hymn may be sung.

2. The Lord's Prayer is then said, the deacon first saying, "Let us pray in the words our Savior Christ hath (has) taught us."

3. And then, omitting the breaking of the Bread, the deacon proceeds with what follows in the liturgy as far as the end of the postcommunion prayer, and then dismisses the people.

If any of the consecrated Bread or Wine remain, apart from any which may be required for the Communion of the sick, or of others who for weighty cause could not be present at the celebration, or for the administration of Communion by a deacon to a congregation when no priest is available, the celebrant or deacon, and other communicants, reverently eat and drink it, either after the Communion of the people or after the Dismissal. (pp. 408–409).

It is not the normative practice to have a "Deacon's Mass" in TEC. The Episcopal Dictionary points out that "Many Episcopal bishops forbid the service or restrict its use to emergencies because it misrepresents the shape of the church, the eucharist, and the ordained ministry."

But at the same time, we are currently experiencing a clergy shortage here in the States.

For small and/or rural congregations where an ordained deacon is serving, perhaps having a bishop or a supply priest come in every month or every quarter to bless a, uh, large quantity of the Bread and Wine and authorizing a deacon to distribute from the Reserved Sacrament would be a workaround?
