what would the total size be if the package included the bios functions?

Probably a few dozen to over a hundred KB, maybe even over a MB, depending on the era of machine and what it has installed; e.g. the GPU option ROM would be included if you use int 10h, int 13h might be hooked by a disk adapter, and if you use int 16h to read from a USB keyboard, that'll go through the BIOS' USB stack which normally includes some code in SMM too.
