well, TE is probably as good of value at 27 as 58, I don't believe it'd be a reach unless Pope and Lewis are gone (Fasano would be a reach there, yes).
Which in that case it'd be stupid to take a guy anyway.
It would be relatively hard to trade up for a back in 2 unless you used the 4th, but it's possible.
It's probably not possible to trade up in 2 to get Joseph, but chances are, Lutui, Matua or one of the more nimble tackles could be there as late as 3. I don't see the need in a 1st round G, personally.
also y2, it's not the same if you don't say "kickass TE" :imagestor
