I could have sworn I'd posted about Thunderhead Studio's excellent and legally distinct "Recursor Coffinmech" before, but it turns out it's been sitting unpublished in my drafts for the last three years because the IP Ogors™ C&D'd it so quick that it was already offline before I could hit publish.
Can't imagine why.
Anyway, they're still updating it and if you're especially clever you can still find the files somewhere out there on the internet. As I've mentioned, this is the objectively correct way to do a bigger dreadnought and I sincerely hope that GW gives the Redemptor the Land Speeder treatment sooner than later.
