Probably not safe at all. SR5 is a descendant of SR4; I know that at my table, we'll generally be assuming that things work more or less the same in SR5 as their SR4 counterparts until proven otherwise. If there's a drastic change, we'll curse and panic, but in general the official gear will be retconned in and it will always have worked that way.
Or did I miss something in your question?
Just use SR4 rules.
Items are placeholders until the new books come out.
Weapons need a slight boost to the damage and an estimate for the accuracy.
Ware costs about 2 to 2.5 times the cost in SR4.
Armor needs a boost but just look at the corresponding armor in 4 and make a guesstimate.
House rule the rest.
I know I'm not taking skinlinks away from my players.
