i think there's a couple interesting concepts in there, and some good feedback in the comments, but i don't know exactly that all the concepts in the original post go together. i think you have a few things going on.
in general, the 2-3 vs 3-2 is all about fg and 3pt defense. it also plays in a big way into depth and balance, but things like offense (especially) and rebounding don't generally function differently than in any other approach. you still are bound by all the same rules of gravity in terms of things like loading up with a ton of per from the 1-4 is probably going to be wasteful, or having crappy rebounding to go along with the crappy turnovers of zone is effectively conceding total defeat on the possession game, which excludes one from being a top tier team.
now, if you are talking about having some flexibility in taking a little less rebounding here or there and having a little more per here or there, because you have these 2 wings instead of 2 bigs - i think there is nothing that says you can't have some per at the 4, and use that to offset lacking per elsewhere. but still, that per scoring from the 4 is rarely going to be super efficient on the 3pt scoring scale, you aren't going to have so much bh and spd that it makes sense to load up on it at the 4, so you still want most of your per scoring from the 1-3. also, you can always use flexibility in rebounding, pg and sg contribute in a big way to rebounding if they have it, and in general folks undervalue reb in the pg/sg - so sure, that sounds fine. i'm not exactly sure how any of this is any different in the face of a 2-3 or 3-2 zone, however.
the one area i see that really ties to zone is the comment about the dominance of press in d3 and bumping the speed to wear opponents down. i think that is an under utilized strategy. a lot of folks build zone to focus on stars, but i like the idea of focusing on uptempo zone and man as counters to the over usage of press in d2/d3. you have to have depth, but i think its totally viable. running uptempo into press is an underutilized counter, but you can't just start doing it, you really have to build the team for it first. and that team very well may be more small ball or per oriented than the average team, because you are prioritizing bh, pass, and stamina (or whatever). i think that could work well for you, but you are REALLY going to have to find a way to be good at rebounding in spite of that. and also i wouldn't over-complicate the relation between the 2-3, 3-2, and any of this - yeah you don't want a straight guard at the 4 in the 3-2 for fg defense, but you don't want it for many other reasons - i wouldn't go that far. m2m would also be suitable for this approach.
