I would do several things to close the gap.
To start with, I would have something called Martial Ability that classes could get. To calculate, just use the multi-class calculations to find out the character's spellcasting level for spell slots, subtract that from the total character levels, and the remainder is the Martial Ability level. So a 9th level Bard would be 0/9, a Fighter would be 9/0, a half caster would be 5/4, and a third caster would be 6/3.
There would be Martial Ability Maneuvers (I suck at naming things, can you tell?) that could be learned. Probably limit their uses to PB per day, but they would scale, say at 7th, 12th, and 17th (arbitrary assigned for purposes of example). There could be a Martial Ability called Rallying Speech, where you can influence one person at first, but then everyone in a huddle, then everyone in 30', then everyone in 90'.
Second step would be to require all expansions to give equal space to Martial Abilities and spells. Also, if they add a spell that lets a spellcaster do something martial like distract someone in combat to give their enemy disadvantage and an ally advantage, add a Martial Ability that does something similar.
