61.87 has quite a few solo requirements in make/model for student pilots, so getting them dual trained in two airplanes seems potentially not worth it. There's an out clause "or similar make/model" essentially leaving it up to the CFI or the flight school to decide what is similar. But heck I wouldn't sign off a student trained on a Cessna 152 for a solo in a Cessna 162. They'd have to be really similar like Cessna 150 vs 152 similar. If the company produce the same plane with electric and fuel power plants it might work. But that's two airworthiness certification processes the manufacturer has to go through.
