Is it possible to rewrite drivers for USB CDC?

Quite often I need USB CDC driver which could be found in Cube Middleware package for communication between PC and uC. It works, but there is a big mess in those functions. I wonder, if it is possible to rewrite my own drivers, with register based code, which could probably be a lot smaller, more transparent and perhaps also faster. Does anyone have any experience with that? USB peripheral looks quite complicated to me. Much more than SPI or USART.
