...and the energy needed to compress stored air into a canister is any less wasteful than an electric turbo? You're going to have to show your work there, please...I don't see itI think it makes sense to get rid of turbo lag. It would also make sense to simply fill up a canister of compressed air when you have excess air in the turbo, then release it in the couple of seconds it takes the turbo to spool, just to fill that gap. By the time your canister is empty, your turbo will be at full speed.
An electric motor is a bit more wasteful, since you are not recovering the kinetic energy from the exhaust gas. In the end the power to run that electric turbo will come from the alternator, so it becomes another load on the engine. But if you want the car to be responsive and don't care much about efficiency... it seems like a good idea to go electric.
I meant when you are driving, after you accelerate to a certain speed you start driving at constant speed, your rpms are relatively high and your turbo is spooled. The car opens the wastegate and releases the excess pressure to the exhaust. My point was you could simply store this excess into a canister, you wouldn't use any more energy than you are already....and the energy needed to compress stored air into a canister is any less wasteful than an electric turbo?

you could store it into a cannister, but now you've added pressure vessel weight to the chassis, the required plumbing to control and pipe the pressure back into the front side of the turbo (remember you can't just dump the pressure back into the turbo from the back, the vanes are not set up for that...and you're literally introducing backpressure into a system that can't run on back-pressure), the added controlling devices etc. You're also adding friction loss from piping, heat considerations due to air being compressed & cooled, moisture, etc...The car opens the wastegate and releases the excess pressure to the exhaust.

The only acceptable wastegate mod out there.. The car opens the wastegate and releases the excess pressure to the exhaust.
Mine was just a wild speculation, but I don't think it's as far fetched as you might think...I guess excess pressure could be stored in a canister, but it'd have to be a big one because the pressure is not that great and the required volume of flow is great. I'm thinking something half the side of the interior of the Ascent. That's just a rough guess.
