Tesla P3D More Power!

Long time member here, I remember back when Mate Rimac was just one of us and not an EV Supercar CEO.

I always have and still want to work on a DIY EV project but was taken by the performance and value of the model 3 performance, so i bought one.

However I would like to get this community's opinions, advice and guidance on increasing the performance of the P3D.

I had a few ideas and once you deem me crazy I would be interested to hear new ideas from you all.

(1) install an independently powered and controlled 3rd motor (Tesla model s front motor) on to a 5th wheel that would make contact to the road under/within the rear trunk.

(2) install an independently powered and controlled 3rd motor (Tesla model s front motor) to the rear of the model 3 and connect the inner cv axles of the oem rear motor and 3rd motor with a belt or chain, on both sides of course, to couple the oem rear motor and 3rd motor together.

(3) install hub motors at the output of the tesla oem motor gearbox and get custom shorter cv shafts made.

I do realize that all the options represent a lot of work and would require material amounts of customization, i guess i am wondering if they are even possible from an engineering and reliability perspective.

Is there another more obvious option I am missing?

It seems to me that all of these ideas are far too complex to make any sense. Just hack the controller for more performance at the expense of lower efficiency and reliability. When the car dies as a result, throw it out and get another one, for less expense than tacking on additional motors and gearboxes.

Hub motors will almost certainly result in LESS power delivered to the tarmac

You may have more power but the additional unsprung weight will ruin the performance of your suspension and as a result you will end up delivering LESS power
Although they were referred to as "hub motors", the state plan was to place them at the drive unit outputs, which would be inboard. If inboard, they would not increase unsprung mass and thus not cause the consequent problems.
