No , would require expensive both structural & design modification , Brahmos is possible but not the EL/M-2248

Not really!

“The MF-STAR antenna includes 4 faces of active array in S-band frequency. The hardware architecture and technology ensure high system availability, low maintenance and low life cycle cost. The EL/M-2248 incorporates a lightweight antenna that can be tailored to fit even relatively small ship sizes (corvettes and above).”

IMHO mainly a modification/replacement of the forward mast (currently carrying MR-775 Fregat MAE/NATO:Half Plate). Along the lines of the P15A model.
Given illuminator enslavement capability for semi-active missiles and automatic splash detection and measurement for gunnery support the upgrade coulad also see removal of the T91E radar, a part of the MR-145 or MR-184 (NATO: Kite Screech) fire control radar system along with a turret mounted Kondensor optical sight, as well as of the six MR-90 Orekh (NATO: Front Dome) illuminators.
I suppose it could also lead to elimination of the EL/M-2221 STGR radars that were installed to support Barak SAMs, replacing 2x AK630 and 2x MR123s, not too long ago.

INS Delhi and INS Mysore have been refitted with the Barak SAM system and the pair of MR-123-02 (NATO: Bass Tilt) directors have been replaced by two EL/M-2221 STGR radars, in addition to deckhouse modifications. Two of the four AK-630 guns aboard INS Delhi and INS Mysore have been removed, to place vertical launchers for the Barak system. As of July 2005, INS Mumbai has not been fitted with the Barak system and still has its original equipment fit. So IMHO INS Mumbai is the most likely candidate (she’s the youngest of the three Delhi’s and is more advanced than the other two vessels in the Delhi Class, although minor modifications are already taking place on INS Delhi and INS Mysore.)
