With a closed end pulpit, depending on length past the roller, a Mantus may fit, as if the pulpit isn't too long, the huge rollbar will fit over it. But other than that, rollbar anchors are likely out unless the rollbar docks to the bottom of the pulpit at a decent angle (will depend on roller geometry).
Personally, I'd take some measurements of your pulpit, then look at the published dimensions for all of the newer generation non-rollbar anchors out there and figure out what will fit best, give good hull clearance in the desired size, etc. And then look at shank shape to figure out if one will launch/dock better in the roller setup than the others.
When I did that on my boat, I found I was most limited by anchor toe to hull clearance, so I ended up choosing an anchor mostly based on that dimension and went with a 73lb/33kg Vulcan. Most of the other designs would have needed to be smaller to fit. An 85lb Mantus would fit my pulpit, although the shank is a bit long for my windlass placement. The only big issue was pulpit length though. The rollbar would fit over the end, but it wouldn't self-launch or dock nicely, it would have required some manhandling, which I ruled out as an option.
