You are now working on the info db, can it have info entries with
dynamic extent? That would also help with
https://bugs.launchpad.net/sbcl/+bug/1289779

So it will look something like:
(info-let ((:type :compiler-layout struct-name) value)
 code which is compiled with that info taking into account)

and that info entry can me modified inside the extent, and the previous
value restored at the end.
