In addition to the objections already raised, you'd need a huge reservoir, and
you'd have to have an oversized turbo to fill it,
which would cut into engine power.

The "hot setup" would be a variable nozzle turbo, with a microprocessor to
adjust the nozzle size according to conditions. For good
off-the-line performance, a small nozzle will accelerate the turbo spool much
faster; while a larger nozzle reduces backpressure for
better performance at high rpm. Such things do exist, but tend to be expensive
and trouble-prone. ISTR that Porsche 911 used them
for a few years, as well as others.
Here's some advertising material on the concept:
