Converting an MGB?

I’m just beginnig to explore the possibilities of convberting a car. Does anyone have any thoughts on the plausibility of doing an MGB? It’s a British two-seat roadster from teh 60’s and 70’s

MG MGB

Its pros seem to be that it is fairly light and mechanically simple and they are plentiful on the used car market. It’s not uncommon to find one that is in decent shape except the engine is shot.

I’m thinking of a car that could do at least a 25 mile round trip. Would such a car be too small to carry the needed batteries?
