I think in terms of the size it impossible .... IMF is not that big to compensate this for the economies involved. It is I think also a bit out the scope of IMF in terms of their goals
I think the role of the IMF should expand its lending facilities through which it can provide needed liquidity at times of crisis like the current crisis.
It is not impossible. It is known that the IMF deals mainly with governments and national authorities. The IMF has updated its mandate in 2012, I do NOT see why it cannot do it again. The IMF could expand and diversify its lending facilities and direct them towards specific sectors and made them project-oriented while maintaining its overall objectives i.e., national authorities oversee and handle the implementation at the micro level while the IMF conducts its regular reviews as stipulated in its mandate.
