Sure. But the P5 are delaying any UNSC reforms, and have been doing so for over a decade now.
Delays in UNSC reforms will diminish its relevance: G4 bloc - Economic Times

UNITED NATIONS: The G4 bloc of Brazil, Germany, India and Japan has said "status quo" and "artificial delays" in implementing the UNSC reforms will diminish the relevance of the United Nations, even as Pakistan called the grouping a "minority" that wants to reconfigure the Security Council to secure "their national interests."
---------------------------
Think about it, if the entire P5 was so eager to let new members in, they would have been in over a decade ago when they first started pushing for it.
Instead it is delays, delays, delays.
That said, I have no problem with India in the UNSC as long as it does not have "veto" power. And so far, no member of the P5 has promised to expand veto powers, let alone all of them.
