80mm rims on a 110mm hub — a bad idea?

I wanted my bike to have nice suspension, so instead of using a Bluto or Mastodon (no offense, but these are very average forks), I took an 80mm rim and laced it with an ordinary 110mm Boost hub. The idea was to put it on a Fox 27.5 PLUS fork. And it works. However...
The problem is that the spokes make a 90° angle with both the rim and the hub. As a consequence, the brake caliper gets in the way, so I've had to file it.
My question: how bad an idea was this? I can fix the scratching of the caliper with a 203mm rotor, but would it be better to, maybe, use a more narrow rim? Or is this generally a bad idea and not a strong wheel?
Reason I'm asking is I'm guessing nobody does this, people just use a 150mm front hub that doesn't have these issues.
Still, I'm curious.

that's a really interesting question, does the wheel stay true?

It does (I think), would you expect it not to?

if the lack of bracing angle of the spokes was causing a problem, one likely issue would be that it wouldn't stay true.

I don't think this is an issue right now.

The Mastodon pro is far better than the Bluto and will fit any tire and rim combo currently made. There's a right tool for the job in this situation.

That Fox fork will still only fit a 4" tire. No need for an 80mm rim on a tire that small.

Filing on a brake caliper to make things fit seems like a bad idea.

I have installed the Mastodon Pro and it sucks as much as Bluto. Compared to the Fox FIT4 damper, those fatbike-specific forks are a joke. They're so bad it's not even funny, like there's a time delay before the forks start to work, small bump compliance is literally nowhere.

I'd have to see it, but I cannot.
