I'm not a mod of the feddit.uk equivalent so it's not up to me, but I'd be cautious about doing so. I have lemmy.ml blocked so I can't see their posts or comments, but I'm a bit wary about their users, it would be like redirecting a unitedkingdom community from hexbear or grad.
Yeah we can reach out to the mods there and see if they'd want to redirect to us.
