Forgive me if I'm missing something obvious, but why are you renumbering at all?
Of course the diversification of RIRs is a good thing, but couldn't that be accomplished just as well by transferring the current allocation to LACNIC?
It seems to me that there are a lot of reasons why, when it concerns root servers, renumbering should be a last resort. Especially when you already renumbered relatively recently and when an administrative solution rather than an operational one is available.
I administer a few public IRC servers for EFnet, and when I assign a /24 for such a server I consider the subnet unfit for any other purpose from that point forward. Practically lost for normal use.
Now, a DNS root server is obviously not the same as an IRC server, but I'd guess that there is a lot in common concerning threats and mitigation of those threats. Only the scale is much larger and the service (much) more critical (though people on IRC will fight me for saying that :).
So, it seems to me that you'd also like to avoid renumbering unless absolutely necessary, if only because it's a waste of a perfectly good subnet.
NB. Apologies for top-posting, a script that is supposed to fix this is started corrupting my emails after an update and I haven't been able to find the problem.
USC/ISI is renumbering both its IPv4 and IPv6 addresses for
b.root-servers.net on 2023-11-27. Our new IPv4 address will be
170.247.170.2 and our new IPv6 address will be 2801:1b8:10::b.
USC/ISI will continue to support root service over our current IPv4 and
IPv6 addresses for at least one year (until 2024-11-27) in order to
provide a stable transition period while new root hints files are
distributed in software and operating system packages.
We are renumbering to increase the resilience of the Root Servers
System by further diversifying the number of Regional Internet
Registries (RIRs) that have allocated IP addresses to Root Server
Operators. Our addresses will be the first in the Root Server System to
have been allocated by LACNIC and our routes will be verifiable through
LACNIC’s Resource Public Key Infrastructure (RPKI) Trust Anchor
Location (TAL). We thank LACNIC for helping make this renumbering
possible, and ARIN for supporting our prior addressing assignments.

translations, can be found on their website here:
