This is like the conversation we've had in the past about Sasaki having multiple kakuhou and my feelings are generally the same. I don't think Sasaki can have a foreign object so easily surgically embedded without his body rejecting it.

Let's step back a bit. Before considering surgical alterations, let's first consider how something like that would work. Sasaki is a rinkaku type ghoul, so has the highest regeneration. On top of that, his regeneration is higher than normal for a rinkaku. Bodies try to reject foreign objects because they don't belong and are read as dangerous. The only ghoul we know of that have undergone some sort of transplant are Kanae (and probably Noro) and it was a terrible experience and it was a very very special circumstance. The transplant was Eto's kagune which is super advanced to the point it has sentience. It can force itself into a body because it literally has a mind of its own.

While it's a popular fanon, it's actually never been confirmed that Sasaki is taking suppressants. The fandom came to that conclusion because Sasaki's Rc Cell count seems really low and it seems logical on the CCGs part to dampen his powers a bit. For the sake of argument, let's say it's a fact though. We really don't know the conditions. Like, how long he's been on them, the dosage, if there are lasting effects, does his dosage flux, and how often he has to take them. Without this information, a real hypothesis can't made. We're just missing too much information because we're never really told how suppressants work.

After two years, Sasaki's regeneration still seems to be pretty good. It looks like it's based on his state of mind more than anything. After fighting Serpent he was afraid that his regeneration wouldn't happen in time, but he healed right away right after he got in touch with his "inner Kaneki". Other times where he's either too unstable or sees himself as "weak" is when his regeneration isn't as good. It's been about a year after the Serpent incident and it still hasn't been indicated that his regeneration has been badly hindered. We didn't see his arm in the last couple of panels of chapter 52, so it' actually not known if it's started growing back. If it hasn't. I chalk it up to him needing to eat something.

TL;DR No, I don't think any of his body parts will get replaced with anything, even on suppressants. There's just nothing in the story that tells us that something's wrong with Sasaki's healing, if suppressants have long lasting negative effects, or if Sasaki is even taking them.
