That's not going to work well - different regulators have wildly
different abilities to deliver current which is the whole reason why
modes are so fuzzy and hard to use in the first place.  A high power
load for a low noise regulator designed to feed analogue circuits might
not even make it out of the lowest power LDO mode of a DCDC designed to
supply the main application processors in the system or (more
relevantly) provide the main step down for a bunch of LDOs.
