TomeAndBlood VS Might_and_Guile

I don't think there's a way to do that without mods. Certainly it's beyond EEkeeper's ability. I guess something like Tome and Blood's Arcanist would sooort of get close (or the 5E casting mod), but I don't think it can multi or dual-class. And even that would only get you a class that learns spells like a wizard and casts like a sorcerer. If you want two spellbooks, one that casts like a mage and one that casts like a sorcerer, I don't think that's possible. T&B's Multi-sorcerer mod lets you play a cleric/sorcerer or druid/sorcerer, but that's the closest thing I can think of.

At least, Shield should be an abjuration spell.

Tome & Blood, Might & Guile, and Faiths & Powers in effect overhaul most of the classes. T&B has some fun options for mages, specialist mages in particular, and sorcerers, including a Favored Soul kit that gains access to a handful of cleric spells. M&G bards are fundamentally different from vanilla classes - multiclass thief/mages or fighter/mages that cast spontaneously and use passive auras rather than active bardsong to aid allies. Very cool. And F&P's sphere system (I've been using nuFnP) makes clerics and druids feel totally distinct from each other. The elemental mystic druid kits feel (and play) totally different from, for example, the Hivemaster. Super fun.

Try this.

and another adds dragon aspect powers and mage kits https://github.com/subtledoctor/TomeAndBlood

it's called Tome and Blood. Highly recommended, this guy makes really cool class/kit mods.

This mod has a component which unlocks the possibility of sorcerer multi-classing. Never tried it but it should be possible to use EEKeeper afterwards to add Kensai specialization to your fighter/sorcerer character.

Might and Guile: Modular. Adds everything from additional thief, ranger, and bard kits to some fun multiclass kits (ie, the halfling slinger, a halfling fighter/thief equivalent of the ranger Archer kit) to a complete overhaul of the bard class, turning them all into multiclasses with passive auras (in lieu of modal bardsong) that cast spontaneously like sorcerers. I haven't played enough with all of these (especially the revised bards) to comment much on them, but the new kits are both distinct from vanilla kits and similar power-wise. The reworked stalker (loses mage spells, gains snares and shortsword/dagger mastery) and beast master (a shapeshifter-lite, it gains a spirit wolf buddy and a wolf and werewolf beast shape) are particular standouts - combined with the Improved Rangers component which adds a reduced backstab multiplier and improved sight radius for all rangers, it does a lot to carve out a proper niche for the class. The thief Ninja kit is also very fun to play, in both its single- and multi-classed versions: it gains several pseudo-magical abilities (such as reflected image, knock, and sanctuary), cast using ki points gained at every other level. There's a fantastic breadth of options, many of which feel well-suited for NPCs.

If you like 3E bards you might like the bard overhaul in Might & Guile, which gives bards spontaneous spellcasting and changes their bard songs into something more like NWN2’s “inspirations” which can be active even while you fight and cast spells (for the most part).

Well, yes, because it doesn't really feel they add much to the table. I wouldn't roll a bard myself either. But then I found the Might & Guile mod which tuned bard kits into multiclass kits... and revamped the songs... and I can see this community doesn't like rulechanges but this became one of my cornerstones of the game.
