Keep the transmission and you'll have much better than stock performance.

I'm thinking in terms of building a vehicle from the ground up, not conversion. For conversion, performance is almost always a trade-off with cost.
However, in a properly-designed production vehicle, I would have the expectation of higher voltages, and thus, higher efficiency and performance.
Still, just stepping up to 144V is significant from 48V in terms of available power.
I am in the blue-print dreaming phase of an all-electric RV. It will have 700V+, should I ever get around to building it.
Also, as for safety? There are several thousand volts going through the ignition system of a traditional ICE, but very few people ever get shocked. As for me, I build tube-based amplifiers, some of which run 500-700v on the plates. Low-current DC, sure, but it's still enough to kill you should you take it across the chest. I've been shocked before, but never fatally. Left hand in pocket, always.
