That would be awesome PR, and not that expensive with starship.

But for low production rate things like telescopes, launch cost is almost negligible even at current launch prices.

A replacement for hubble could be launched with a single falcon 9. Building it would cost more than a billion.

The James Webb Telescope is at 10 billion USD and counting. Launch with very expensive Ariane 5 will cost maybe 200 million USD, so ~2%.
