I think that's a very interesting idea with the pvp weapons being used on items such as the dwh and like a zammy spear. This would not only make pvming even more worth while but also help the wilderness out a lot. If this would be possible i'd for sure wanna see this added in game with the exception that the people with pvp weapons currently would be compensated if they were to remove all pvp weapons in game, however if they can't do this I think just making the pvp weapons work at corp would be enough to make people more inclined to entering the wilderness and trying to snipe a pvp weapon for new bis items at corp. Either way the max hit cap at corp is 50 so this honestly wouldn't be bad at all.
