It is observed that voltage change in given rail affected by the load
and the capacitor in the rail. This may cause the slow ramp in voltage
against what PMIC has programmed.

The regulator-ramp-delay is a variable you can tweak on a board basis,
so I'm not sure what benefit it gives to be able to add a scaling
factor to this.

In my experience your HW engineer will say "you have to wait X ms", not
"you have to wait 125% of X ms".

Can you please elaborate on why the original knob isn't sufficient?

Right, this definitely feels like the wrong thing is being specified
here (and also like the PMIC might be going out of spec, possibly as a
result of being overloaded) and that the existing board specific
controls should be used.  It just doesn't correspond to the way people
usually talk about specs for PMICs.
