has anybody adopted this form?
Yes. Christians adopted it to build larger and more handsome edifices for worship
Basilica
Christians were prepared to build larger and more handsome edifices for worship than the furtive meeting-places (such as the Cenacle, cave-churches, house churches such as that of the martyrs John and Paul) they had been using. Architectural formulas for temples were unsuitable due to their pagan associations, and because pagan cult ceremonies and sacrifices occurred outdoors under the open sky in the sight of the gods, with the temple, housing the cult figures and the treasury, as a backdrop. The usable model at hand, when Constantine wanted to memorialise his imperial piety, was the familiar conventional architecture of the basilicas.

Basilica [SEP] Christian adoption of the basilica form
The usable model at hand, when Constantine wanted to memorialise his imperial piety, was the familiar conventional architecture of the basilicas. There were several variations of the basic plan of the secular basilica, always some kind of rectangular hall, but the one usually followed for churches had a central nave with one aisle at each side and an apse at one end opposite to the main door at the other end. In (and often also in front of) the apse was a raised platform, where the altar was placed, and from where the clergy officiated. In secular building this plan was more typically used for the smaller audience halls of the emperors, governors, and the very rich than for the great public basilicas functioning as law courts and other public purposes.
