The Answer depends on the school one asks.
The Thenkalai school of sri vaishnavism for instance, does hold that the The Liberated Souls can attain the power to create their own universes etc. if God grants them the power to. Copying from this answer in the below section -
Here is what Ramanujacharya says in his Sri Bhashya in sutra
4.4.14:
In the same way as the highest Person creates out of himself, for his
own delight, the world of the Fathers and so on; so he sometimes
creates such worlds for the enjoyment of the released souls. But
sometimes, again, the souls using their own creative will-power
themselves create their own worlds, which however are included within
the sphere of sport of the highest Person.
But there is one caveat to this, and that is explained in sutra
4.4.17:
The released soul gets all the divine powers except that of running
the universe (with its creation, continuance and dissolution), as is
known from the context (which deals with God) and from the
non-proximity (of the individual soul).
Which means that the liberated souls cannot interfere in the creation, sustenance, and destruction of the universe that is common to the
Jivas bound in samsara, but they can create, sustain, and destroy
their own worlds that are separate from the universe of the Jivas
bound in samsara.
In the Skanda Purana, Sage Vishvamitra obtained the powers of creation( rivalling that of Brahmā, The creator of the universe )from Shiva as a boon after he pleased Shiva through his devotion.
Viśvāmitra said:
‘O Lord of Devas, if you are pleased, if a boon has to be given to me,
O Maheśvara, let me have the great ability of creation with your favour.
After saying “Let it be so” the holy Bull-emblemed Lord vanished from there along with all the Gaṇas (attendants).
Viśvāmitra stationed himself there with due meditation. Rivalling
with Brahmā, the Lord moving about on his Swan, he began the creation
of four types.
With Shiva's boon, the sage created everything Brahma can create even Devas, Asuras, stars and planets, humans etc. so basically his own miniature universe.
With a keen desire, he entered water and began to meditate. Then he
created two Sandhyās (Twilights). O Brāhmaṇas, they are to be seen
even today.
Thereafter all the groups of the Devas were created by that
noble-souled one. Persons travelling in aerial chariots, stars and
planets, human beings, serpents and Rākṣasas, creepers and trees; the
seven sages (Great Bear), Dhruva and others (Pole Star etc.) and
sky-walkers were created.
After creating these, the angry sage Viśvāmitra employed them in his
own work. At that time two suns and two moons rose up in the sky
simultaneously. There were two sets of planets. Two sets of stars
along with the Great Bear came up, O Brahmana.
So under certain constraints, Such a power can be attained at least as per certain schools or scriptures
