This can be addressed by using tunnels to create multiple hops.

See for example: Tunneling tunnels within tunnels (inside of tunnels) — https://cryptostorm DOT is/blog/multitun (I broke the url because otherwise HN is incorrectly marking the comment as [dead])

It would be great if Mullvad adds multi-hop support (>2) based on something like that.

Another possibility is to create a VPN on top of a Mixnet like Nym: https://nymtech.net/.
