If I thought the Oline was good enough to keep intact, I would. I'm not sacrificing quality for continuity, and I personally am of the mindset that depth is as important as the starters, because most years, you're going to go extended periods of time in-season where your starting five Olineman aren't playing together due to injuries. One of the main reasons why fans undervalued somebody like Hurst, and Mekari, who were effectively average players at four positions. And to the surprise of nobody who has followed the NFL, they end up having like 10+ year careers, even though the fanbase thinks they suck. This has actually been one of the healthiest teams in terms of Oline play in the entire league, and they're still nothing more than hovering around the league average. That's not great.
IF we were talking about Tackles, I'd be on board. I think finding an upgrade on Stanley or even RR is a very difficult task in the current OLine shit show that is the draft. But what's clear is you have two Guards who are replacement level starting right now.
In reality, we're talking about Linderbaum and Linderbaum only. I think its impossible to argue that Faalele or Vorhees are good enough that you can't easily replace them. That's a foregone conclusion.
I brought up the tag because, since we declined his 5th year option, and haven't extended him, you can't really control if he returns or not. In order to keep him, you either have to pay what every other team in the league will pay for him (which could be a lot), or you have to tag him, which is at above market value. Other than that, whether he stays or not may not be up to you.
