Would make sense as an end goal, curious if they'll be on show before then however. Only place I could see them going would be along the canal islands or potentially mixed with the mandrills though not sure that's ideal considering they'd both be breeding groups.
If (reasonably big 'if' of course as they easily could be offshow for some time) they were going on show more-or-less straight away then I think the canal walk enclosures are probably the only reasonable option - possibly with a lemur reshuffle to make space.
