now as cv's showed parvati cursed devtas can't have children so they can't show devsena as indra's daughter..but as in some versions she is vishnu's daughter so it definitely can be shown..because as vishnu-laksmi also supreme god-goddess same as shiv-parvati so their daughter can born from meeting of two souls just like shiv-parvati's son kartikeya...
and the idea is vishnu willingly sent his daughter devsena to indra's palace as he was aware of indra's evil plan of sending an apsara to distract kartikeya..and the incident of indra saving her from asuras was also a trick by tridev...
this idea though illogical but far more better than making devsena just an apsara and wooing kartikeya in bollywood style...
its just my pov..sry if anyone doesn't like
