Take a look at these mods. I think they may help cater to what you are looking for. While I'm not using all of these now, I found them to be very well done when I did. (I'm using Diverse Races, Level Rates Modified x3 included with OOO 1.3.1, thinking about using AF Level Mod). All of them should be available from The Elder Scrolls Nexus - Oblivion mods and community
. It's has a TON of mods to download...
Let me know if you can't find any of these and I can email some to you. OOO for instance is a monster at 423MB, but should be pretty easy to find on the web.
Newer versions may be available, though these are the ones I have downloaded. Oh yea, any of them should compliment other mods such as OOO, Mart's Monster Mod, & Francesco's Leveled Creatures nicely.
Brief intro from mods readme file:
Diverse Races v2.0
It has long been the Elder Scrolls way that every race could reach the score of 100 in every attribute. While this is nice, it rather made choosing the race boring and mostly cosmetic. Worse yet, it destroyed any potential a race is said to have according to the lore; a fully developed Orc would be no stronger than a fully developed Altmer, and a fully developed Imperial would be no more charming or intelligent than an equal Khajiit.
This mod changes things a bit. Now, depending on your race, you'll be able to take at least two of your attributes above 100. Of course, nothing comes without a price - some of your attributes will be capped below 100.
Kobus Character Advancement System
(ver 2.4.1) -
Kobu’s Character Advancement System (KCAS) replaces the standard Attribute gain at Level-up with an intuitive and natural Attribute and Level gain system that is fully customizable. KCAS makes it so you will never again have to track your Skill gains or engage in metagame tactics to insure optimal character progression. KCAS is designed to be fully immersive and integrate seamlessly with your gameplay. You can use KCAS with both new and existing characters.
SD Skill Diary (ver 1.3) -
The skill diary is intended as a useful tool to allow players to track how much each of their skills has leveled up since the last time they gained a level. From this information it is possible to determine better which skills to focus on in order to get the desired attribute multipliers for each level.
AF Level Mod (v 2.8.7) -
The intention of this mod is to fix the annoying parts about Oblivion's Player
leveling system and keep intact as much as possible in the spirit of the
original game. To create a mod where you can play it and have fun and not
worry about micromanaging X5 Multipliers, and be able to level up a character and not "GIMP" him by not training the right skills at the right times
Level Rates Modified x2 - x5 v1.3.1 (4 separate files included in OOO 1.3.1)
Most skills Most skills level twice as slow, 3x, 4x, or 5x as slow as vanilla oblivion.
I keep thinking there is another mod besides Kobus CAS which you level up based on all skills and not just majors. If I come across it, I'll post the info.
Hope this helps.
