This idea is a rough sketch and has not (yet) been extensively play-tested. Many thanks for your advice.
I like your idea of some simplified system, as a framework/alternative for groups who would enjoy some type of inter-level milestone system, but without excessive complexity. I think we're basically in agreement that the idea has some merit and could be fun, in some form, and that a reasonable system will not greatly unbalance game play.
Even within the same group, if some players choose to use an inter-level system and others do not, relative character strengths will re-balance at official XP levels (assuming the game is balanced as officially written). Some players may even enjoy the slight additional challenge of playing a non inter-level advancing character in a group of inter-level advancers.
Since all encounter levels are somewhat approximate and the GM has enormous flexibility to tweak encounter difficulty in a myriad of ways, it is difficult to imagine any way that an inter-level system could seriously undermine game balance.
I think the main issue you were raising was the complexity of the system relative to the game-play enhancement it might offer. This is going to vary dramatically between different gaming groups. Players who play Pathfinder on Wednesday night and War in Europe on Sunday are not going to have a significant problem working with a highly detailed inter-level system. More casual gamers may desire a much simpler plug-and-play system with no math required.
Some form of inter-level XP system should be available to both types of groups.
Here's some thoughts about the categories of increases that you list, in a more detailed inter-level system:
Hit Dice: If desired, a player can roll hit dice for the next level and use each point of that total gain as a separate milestone item. This would introduce a much smoother accumulation of hit points and create a larger number of milestones between levels. Again, if desired.
Skill Points: Similarly, each individual skill point could be made a separate milestone item.
BAB: This might be one of the items that should be awarded only at full level attainment. Certainly it should be if it adds an additional attack. BAB increases could be made inter-level milestone items but with the requirement that they be the last ones chosen unless they are 'unlocked' by the GM (for good role-playing or heroic in-game acts).
Spells/Spell Level: New spell levels and caster level should probably be a full level achievement. Spell slots could be inter-level milestone items unlockable by the GM for relevant in-game actions.
Saves: Defensive in nature, increases to saves should be freely available as inter-level milestones.
Class Features: If approved as inter-level milestones these should taken last or as unlocked by the GM.
The early unlocking of locked inter-level milestones is something the PC must earn. Since these milestones reflect the class/role of the character, this encourages the player to act very much in the spirit of the character's class/role. This should have a positive effect on game play.
Example 1 (revised):
Ardamir, L4 Human Wizard
Ardimir rolls a 4 on d6 for L5 hit points. With a high intelligence, he gains 5 skill points per level.
List of L5 benefits:
caster level +1
3rd level spell slot
bonus feat
hit point (x4)
skill point (x5)
The GM rules that "caster level +1" and the "3rd level spell slot" should be gained only on full completion of normal L5 XP requirement. The other ten items are placed on Ardamir's inter-level milestone list.
Using Medium XP leveling, the difference between L4 XP (9,000) and L5 XP (15,000) is 6,000. Therefore Ardamir has ten inter-level XP milestones at:
9545
10090
10636
11181
11727
12272
12818
13363
13909
14454
The GM rules that "bonus feat" is locked and must be taken at the 14454 XP milestone unless Ardamir acts heroically in-game and unlocks the bonus feat at an earlier point.

I'll leave the idea here as is; I have nothing more to add at this point. My next step is to play-test it with my new group. If I get some interesting results, either positive or negative, I'll post a followup. Any further comments or advice is deeply appreciated. If anyone else play-tests any variant of an inter-level XP system then I would appreciate hearing about your group's results.
