here are a few equations you should get used to when estimating EV conversion.

・Range(mile) = PackSize(kw) / efficiency(wh/mile) x80%
the 80% is there to ensure you wont be using 100SOC of the cells
・efficiency(wh/mile) = Weight(lb) /10

Power =(mass x 9.81 x velocity x Crr) + (0.6465 x Cd x Area x V^3)
this will give you how much power required to go at specific speed you have in mind

Crr = Rolling resistance
Cd = Drag of your car

Area =Frontal Area in m^2

Given all these info, 28kwh will only be good to 70miles with extremely aerodynamic car.
Leaf motor will not be able to give you the Hp you want.
(1hp = 746w of power, therefore in theory you need 298.4kw rated motor...)

I think you need alot of reading before you can start spending your money!!

Quick answer I believe is No.

I have no knowledge of both cells but if they have different capacity(Ah) or a characteristics than they will not work
it's like wearing two different shoe on each feet. At first, you feel like it can work but eventually you will feel unbalanced and eventually one will wear out faster than the other...
