I don't know if this has been suggested or is a truly novel idea but instead of the MT using the +1/+1 level of spellcasting classes why don't we just fuse the spell lists and use +1 level of current spllcasting class.
MT's are then mages who learn to prepare some low level divine spells or clerics who learn some low level arcane spells.
This means that a starting character can advance one spellcasting class to Level 5 to become an MT. For prerequisites we can require that they spend a feat or two and maintain both knowledge religion and knowledge arcana at max ranks (which would be five for both classes under the Pathfinder skills rules which just add a +3 bonus to class skills.) I know that this favor wizards slightly but it makes much more thematic sense for wizards to try to simulate divine effects than for clerics or druids to try to find a way to go beyond the gifts of their gods.
Upon entering the MT class the character then gets to add 1st level spells of one opposite spell casting class (wizard/sorceror, cleric or druid) to their spell list as though they were spells of their starting class (e.g. wizards still suffer arcane spell failure penalties even when casting cure light wounds).
For example a character advances as a cleric for 5 levels picking up the prerequisite feats and the necessary skill ranks. (Which means they contribute normally to group survival).
At level six the character becomes cleric 5/MT 1. She then has all the powers abilities of a 5th level cleric. In addition she has the same CL and spell slots as a 6th level cleric. She can fill those spell slots with any cleric spell of levels 1-3 as normal AND any wizard/sorceror spell she learns of 1st level or lower. In addition she can use any items normally usable by a 6th level cleric or wizard/sorceror.
When she reaches level 7 (cleric 5/MT 2) She has the powers and abilities of a 5th level cleric and the spells, spell slots and caster level of a 7th level cleric. In addition she can choose to fill those spell slots with wizard spells of 1st-2nd level that she learns.
If the character had started as a Wizard then, she could prepare cleric spells when she becomes an MT.
This system maintains the power level and spell slot exhaustion rate but gives versatility in kinds of spells and magic items available rather than spells per day.
Few extra points:
All spells of the new class should be learned from spell scrolls if the base class is cleric, wizard or druid (which works thematiclly since its either a divine caster learning an arcane spell or an arcane caster learning how to simulate a divine effect).
Sorcerors learn spells of all their classes via the standard spells known system choosing from among all the spells available to them from both class lists. In addition, upon entering the MT class sorcerors are allowed the opportunity to swap any 1st level spells with spells from the new additions to their class spell list.
I'm sure there are some details I missed but this might make the MT more playable by giving versatility to what they can do rather than how often they can do it. It should also keep them from being being underpowered for the first 5 levels or overflowing with magic at the top five levels.
It's also fully backwards compatible since it effectively just expands the class spell list for the MT.
