It's a great card but I think it would still be too slow as a tutor. The Shroud effect could be interesting though, but I am not sure how much it is really needed.
I hope that they put a Steelshaper's Gift in Modern Horizons that searches for an Aura instead of an Equipment card.
An aura-centric Steelshaper's would be excellent and seemingly much more likely than Enlightened Tutor entering Modern.
I think we'd benefit from almost any sort of efficient card advantage/filtering and/or tutor effect. I still think Sylvan Library would be a fair addition to the format and give us some filtering/painful CA while juicing up Ethereal; with the exception of DS decks moving into green, I don't see many ways it could end up being degenerative. I definitely agree with Grove being a slow tutor, but I think there's potential there if we can take advantage of shrouding our enchantments. There could be some utility in running it out of the SB either alone or with some kind of misc non-aura enchantment package (e.g. Suppression Field, Ghostly Prison) to slow down/turn off any enchant hate by tutoring up another copy in response to removal. I suppose it would allow us to drop a Daybreak with only 1 other aura attached without needing to worry as much about losing both to a removal spell. Might not ultimately pan out, but thinking back to when Open the Armory was printed and desperately trying make it work, I'd definitely like to give it a whirl if it should enter the format.
