thinking of converting AWD Volvo XC90 without using transmission

Hi,
I am a new member and this is my first post...please bear with me and go easy on my ambition here....
I want to convert my faithful, but beaten up, 2005 Volvo XC90 AWD SUV to electric. And I don't want to keep the transmission...want to connect directly to the drive shaft if I can. My aim is to have a range of minimum 100 miles (ideally 150) and highway capable. If I understand it right, this model has a curb weight o f about 4200 pounds. In connecting directly to the drive shaft, do I loose the AWD functionality of the car (if I am being illogical here, please bear with me). And also, would like to use the LiFexx batteries and not lead acid. Also, how does the car's computer system react to ripping off the transmission?
And what kind of budget am I staring at (rough ball park).

Thanks for your time.
