Hey Ben, lovely to read your message here and it’s great to have you on the team using Huel. I definitely can do it - what are you aiming for?
I would piggy-back off what @David has said about going 100%. If I’m honest, I would keep it at a few Huels plus your HelloFresh meals if you feel like 100% Huel is too much. I’ve written some comments to someone else whose goal and plan has similarities to yourself. I think it’s important to make changes to your diet that you can maintain long term, we don’t see Huel as a short term diet option but more a sustainable change to your diet, long term (but we would say they eh?!)
All the best to you, and do keep us posted, read around the forum and chat with others too. Great to have you here.
