This is somewhat less ambitious than changing the whole structure of the degrees, embedding real life work experience into the education process itself, and in some cases, upending the traditional education process completely with a competency-based model. That model is of greater value than just opening up internships to those who can not afford. But that is also more difficult, given the different cultural and social meaning that are embedded in education. A majority of British undergraduates still rate Social Experience as the main reason for choosing a college, deferring the career worries only until later. The higher education as a middle class ritual is far more complex to challenge than the internship as posh privilege, which middle classes want to get a share of.
Can a meaningful intern experience be built online? At the least, this ought to be easier than replicating a whole university out there, which other people have done. This may need to go far beyond just connecting candidates with opportunities, including providing a managed space where the work could happen, and the candidates can get feedback and earn credits that they can later use with employers. This can also be the space they can learn useful job skills, communication, collaboration, prioritization etc., and connect with recruiters looking for their areas of expertise and experience.
