I'm not exactly enthused about the idea of another edition anytime soon, but, sure, it's possible.
3-4 encounters, maybe
Depends on what folks whine about the loudest..
Instead of x number of encounters, wouldn't a better (and simpler) move be to do away with the short rest mechanic entirely and simply accept the short adventuring day as the norm? I'm not saying I like the short-day model, but when resources return on a daily basis it only makes sense from the point of view of the adventurers themselves.
I mean, it's a whole spectrum - the designers just have the unenviable task of figuring out where to land on it. Let's look:
Recoverable resources: hit points/hit dice/health/stamina - spells/mana - limited-use abilities (LUA) e.g. Druid shapeshift
Spectrum: (just for resting, ignoring cure spells etc.)
- everything is fully reloaded after every encounter
- hit points and spells are fully reloaded after every encounter but LUA have to wait until overnight
- hit points are fully reloaded after every encounter but spells and LUA have to wait until overnight
- spells are fully reloaded after every encounter but hit points and LUA have to wait until overnight
- everything has to wait until overnight but is fully reloaded in the morning
- everything has to wait until overnight but only spells and LUA are fully reloaded in the morning with hit points only partly reloaded (this one's my preference, with the h.p. reload being minimal)
- everything has to wait until overnight but only LUA are fully reloaded in the morning with spells and hit points only partly reloaded
- nothing fully reloads overnight but if two (or three, or however many) consecutive nights are spent resting then a full reload happens for all
- resting in the field does nothing at all; the only way to get anything reloaded is to spend a few days in town
