Many parishes implement RCIA according to their own rules rather than what is in the rite. RCIA is intended to be flexible, meeting the needs of the specific catechumen or candidate. In many places it is offered simply as a class. You attend for six or eight months and "graduate" by receiving the Sacraments of Initiation.
You can certainly ask to be received into the Church at another time. For those who are already baptized, this is exactly what the rite envisions. Depending on how wedded your RCIA director and pastor are to the classroom/graduation model, they may or may not agree.
I would recommend that you speak first with the RCIA director and then the pastor. In my parish, the pastor wouldn't say yes without consulting with me first about my impressions of the candidate's readiness. If this was the first I was hearing about it, that wouldn't be a good sign.
I would add from the U.S. Conference of Bishops, National Statues for the Catechumenate, Nov. 11, 1986 (page 368)
Those who have already been baptized in another Church or ecclesial community should not be treated as catechumens or so designated. Their doctrinal and spiritual preparation for reception into full Catholic communion should be determined according to the individual case, that is, it should depend on the extent to which the baptized person has led a Christian life within a community of faith and been appropriately catechized to deepen his or her inner adherence to the Church" (NSC 30)
Those baptized persons who have lived as Christians and need only instruction in the Catholic tradition and a degree of probation within the Catholic community should not be asked to undergo a full program parallel to the catechumenate" (NSC 31)
"[t]he reception of candidates into the communion of the Catholic Church should ordinarily take place at the Sunday Eucharist of the parish community, in such a way that** it is understood that they are indeed Christian believers who have already shared in the sacramental life of the Church** and are now welcomed into the Catholic Eucharistic community . . . " (NSC 32).
"**It is preferable that reception into full communion not take place at the Easter Vigil **lest there be any confusion of such baptized Christians with the candidates for baptism, possible misunderstanding of or even reflection upon the sacrament of baptism celebrated in another Church or ecclesial community . . . " (NSC 33)
Note that while (NSC 32) states "the reception of candidates into the communion of the Catholic Church should ordinarily take place at the Sunday Eucharist of the parish community" reception can take place during an ordinary weekday Mass, or if necessary even outside of a Mass. I myself was received in a weekday Mass 25 years ago and we have candidates received in daily Mass or Sunday Mass depending on the choice of the candidate in conjunction with our pastor. As noted in the Statutes, the U.S. Conference of Bishops upholds the preference that the Easter Vigil be for the Initiation of the unbaptized, recognizing the dignity of baptism for Christians seeking full reception into the Church.
