Yessir.

Now, given that I've spewed all this information over your idea.. it can only cost a dollar or so to try it out. So try it out! Once again, there might be something I'm not taking into account, and I'm far from an expert, so you shouldn't just take my word for it.

I do recommend that you check the voltage on that vacuum pump and vent solenoid during their operation and resting periods though... you might be able to modify the voltage so that there is less vacuum modulation during deceleration. (Make the vent solenoid open further to allow less vacuum to be applied to the diaphragm, or limit the voltage to the vacuum pump itself.)
