Given the fact that the sacrament of Confirmation can be delegated to the parish priest, it would not seem out of reason totally that the institution of a lector or acolyte could be also delegated. However, given the fact the there may only be less than a handful of bishops who actually institute anyone (Vasa being one of them, I believe), the question would almost seem to be moot.
Outside the Easter Triduum, it requires specific letters of authorization for specific candidates to be confirmed.
One can assume no less strict a requirement for instituting Lectors and Acolytes.
Installing lay readers and lay altar servers is specifically within the competence of the pastors (within the US, at least)…
Relevant Canon Law on Lectors and Acolytes:
Can. 230 §1. Lay men who possess the age and qualifications established by decree of the conference of bishops can be admitted on a stable basis through the prescribed liturgical rite to the ministries of lector and acolyte.
Nevertheless, the conferral of these ministries does not grant them the right to obtain support or remuneration from the Church.
§2. Lay persons can fulfill the function of lector in liturgical actions by temporary designation. All lay persons can also perform the functions of commentator or cantor, or other functions, according to the norm of law.
§3. When the need of the Church warrants it and ministers are lacking, lay persons, even if they are not lectors or acolytes, can also supply certain of their duties, namely, to exercise the ministry of the word, to preside offer liturgical prayers, to confer baptism, and to distribute Holy Communion, according to the prescripts of the law.
Can. 231 §1. Lay persons who permanently or temporarily devote themselves to special service of the Church are obliged to acquire the appropriate formation required to fulfill their function properly and to carry out this function conscientiously, eagerly, and diligently.
§2. Without prejudice to the prescript of ⇒ can. 230, §1 and with the prescripts of civil law having been observed, lay persons have the right to decent remuneration appropriate to their condition so that they are able to provide decently for their own needs and those of their family. They also have a right for their social provision, social security, and health benefits to be duly provided.
Can. 910 §1. The ordinary minister of holy communion is a bishop, presbyter, or deacon.
§2. The extraordinary minister of holy communion is an acolyte or another member of the Christian faithful designated according to the norm of ⇒ can. 230, §3.
Can. 943 The minister of exposition of the Most Blessed Sacrament and of eucharistic benediction is a priest or deacon; in special circumstances, the minister of exposition and reposition alone without benediction is the acolyte, extraordinary minister of holy communion, or someone else designated by the local ordinary; the prescripts of the diocesan bishop are to be observed.
Can. 1035 §1. Before anyone is promoted to the permanent or transitional diaconate, he is required to have received the ministries of lector and acolyte and to have exercised them for a suitable period of time.
§2. There is to be an interval of at least six months between the conferral of the ministry of acolyte and the diaconate.
