A hybird Nikon SE/EII ~8x32 (or 7x32, or 8x35, etc):
- use the SE body but reduce the ER to midway between that of SE and EII (reduce blackouts)
- increase the SE FOV to ~midway between the two as well (say 430')
- add adjustable eyecups
- increase the bridge stiffness
- increase WP properties ONLY if not a compromise to view - otherwise, leave as is
APS
You don't have to reduce the ER. You have to make the mechanical design of the eyecups (their adjustment range) match the ER for more users. That should be easy with a multistop eyecup rather than a two step rubber eyecup. The problem for blackouts is the all the way in stop needs to be further out (or an option to have a further out one as the all the way in stop is probably a win for a hyperope with not very tight fitting glasses).
As I also suspect these EP have some SAEP an EP redesign might be more useful to reduce blackouts i.e. use some of the EP designs used in the Chinese ED (5 element with LaK glass a decent ER).
