Sure you can do all that. That might be cool!!
Some already have done stuff like that.

Is this actually a better way to do it? I dunno. Does Ford have a better idea?
I plan to use a generator to extend the range in the near future and install some type of regen capability. If the generator won't fit, I'll haul it with a little trailer of on the back like RVs do.
Is a "waste of money"? depends...
How much money does it cost others here to dress up, lift up, paint up, power up or generally F' up thier trucks?
Since putting it on the road, I haven't used any gas or required any normal maintenance costs from oil changes, engine parts, ect. I'm allowed to plug in at work for free and don't contribute to air or noise pollution. As for now it only burns electrons.
Since I don't smoke and don't drink (much)

and I work on my own cars, I figure I can piss away some money on stuff other than gas and have some fun at the same time.
