Try again. Tying caster level to character level would do very little to balance out a Wiz10/Cleric10.
The MT goes much farther in making that type of multi-class viable.
I wouldn't say it's only a "very little" change in balance, but I agree that a MT makes a Wiz10/Clr10 more viable than just this change.
Still, It wasn't earth shattering and had some effect. I believe that on this basis, some mechanism could be found.
The problem I have with MT is that it's a specific fix, and it would require many PrC. But I'll adress why it''s not a good thing below.
And how is the addition of 20 or so prestige classes unmanagble? You still seem to be assuming something which i'm not.
With all the existing spellcasting PrC I would have figured it was more than 20. Kinda Like #SpellcatingClass * #SpellCastingClass, even if you don't have to make them all

. Well they could be automatically generated by some prog, and it's probably why it's not a good thing flavorfully IMO
When confronted with a multiclass combo that involve an existing PrC but is weakened by the current mechanism, I see the following choices
1- Bear with it. You want this flavor, but it only come with poor efficiency. Some DM and PCs can deal with very important differences in power between PCs. Some can't or don't want to. I'm in the latter category.
2- You have to take levels in this BaseSpellCastingClass1/ baseSpellcastingClass2 combo WotC made for you
and you might have more power, but you'll have less levels to spend in the class you wanted to raise.
3- Ok, I'm a good DM I'll alter the PrC you want by adding some "MT-like" changes, but It will take some time as I must do a mechanical fix with class abilities while keeping flavor and a bit of balance.
I'd prefer a choice instantly applicable that keep flavor and respect the player's choices.
Unfortunatly, allowing a character to advance the 'way they want' without tying them into a class is a formula for all the unbalancing crap that goes on in most point-based systems.
Are feats tied to a class ? No, but their number is controlled by level. I'm not advocating a classless, levelless system here.
By "the way they want", I just mean something like : I want to be a cleric of "whatever" that is also a bard and will be some kind of spy for his church.
And I don't want to answer him/her with " well you can but you have to take MT levels or you will never be able to pass opponents SR"
how much do you actually loose in character flexibility by taking levels in the MT? It gives the bulk of features of any spellcaster; spell choices.
By looking at Spellcasting PrCs that my players want, I think it's their flavorful powers and not the spell choices that make them interesting, whether they have full spellcasting progression or not.
MT-like classes don't solve their problems.
A mechanic might.
