Not really. According to the
Caltrain Compatibility Blog, the main conflict in the whole CHSR proposal is whether to integrate the Caltrain peninsula services with the standards of the HSR program - in particular common boarding platforms, which would mean a universal platform height. In the end, even with the current "bookend" approach currently under discussion, I think full compatibility will win out. It makes the most sense. They are serious about building a 21st century system that is designed to be a success. There shouldn't be much hesitation when it comes to something as fundamental as different rail equipment sharing the same platform.
Of all the reading on the CHSR program I've seen no evidence that they are considering something along the lines of a low boarding Talgo carriage. Instead, standard high level boarding has been specified.
