There isn't much reason to use lugs at the best of times, except as a look. So if one wants the lugged look it's probably as worth while to have to do a little fabrication as any of the other time wasting involved.
I thought of this as I was typing, but decided to leave it in anyways...
to be perfectly honest, I think that if I wanted to build a frame with an unavailable lug, I would likely follow that route to maintain a uniform look.
Although it does seem a little odd to basically be making a potentially weaker part with what amounts to a 'sheath'
But who said anything about being rational
