Once immorally conceived in a Petri dish, instead of through the loving marital action, should 'surplus' embryos be discarded or would it be morally right to implant an embryo to save it.

I think this article of Dignitas Personae clarifies in my mind that it is not right and we must not cooperate with evil:
With regard to the large number of frozen embryos already in existence the question becomes: what to do with them? All the answers that have been proposed (use the embryos for research or for the treatment of disease; thaw them without reactivating them and use them for research, as if they were normal cadavers; put them at the disposal of infertile couples as a “treatment for infertility”; allow a form of “prenatal adoption”) present real problems of various kinds. It needs to be recognized “that the thousands of abandoned embryos represent a situation of injustice which in fact cannot be resolved. Therefore, John Paul II made an “appeal to the conscience of the world’s scientific authorities and in particular to doctors, that the production of human embryos be halted, taking into account that there seems to be no morally licit solution regarding the human destiny of the thousands and thousands of ‘frozen’ embryos which are and remain the subjects of essential rights and should therefore be protected by law as human persons” (n. 19).
However, I am very impressed with the 'Yes' arguments and to avoid post conciliar stagnation, i'd welcome lively debate around this issue. From a doctor's point of view, I'd want to know the practicalities eg. Consenting biological mothers for donation rather than just storage. An interesting topic. As John Fleming says regarding Dignitas Personae
It’s as if the church is saying to the secular world: “You created this situation by wantonly and irresponsibly creating human embryos in vitro and you are asking the church to solve the problem. It’s up to you to solve this unjust situation yourself by stopping creating embryos outside the body and freezing them.”
