If you're bringing Corp back, whatever item you make it drop should be 1) untradeable 2) degradeable. First would minimize the blow to economy as you couldn't buy those drops no matter how much gold you could transfer from EoC and it's RTW-filled economy. Making it degradeable would force players to keep killing Corp if they want to keep their new best-in-slot items. For example, if you decide to bring back spirit shields make it so that after absorbing 10k dmg entire shield dissolves and you have to grind Corp for new one + sigils. Base spirit shield could remain non-degradeable until sigil is added and the quantity of absorbed damage would depend on sigil. As long as Spirit Shield drops would be rare and sigils even rarer, this could be a compromise between people wanting new items & and keeping them from being blatantly game-breaking like Spirit Shields were in pre-EoC RS.
As for requirements to access it, 200+ Quest points and 110+ Combat Level should be absolute minimum requirements. Ideally you could introduce it with new quest as part of some new area in progress, there's no real need to put it in Wilderness as Summer's end doesn't & cannot exist in RS so Corp's backstory is in need of revamping anyway.
Also for folks lusting after Grand Exchange, just stop it. Runescape is already barely multiplayer game as it is, introducing GE would kill off remaining player interaction that currently happens via trading. It would also hurt economy by making it far more prone to meddling & drive prices down via massive ease of access.
