If we assume a linear progression, then one could argue that you may take a +1 to hit for every -1 to your defense that you're willing to give up. We could simply have a Determined Attack option (like Telegraphic Attack [MA113]) and drop the All-Out Attack (Melee) Determined and Committed Attack (Melee) Determined maneuvers.

Determined Attack (Melee)
Replaces the rules for All-Out Attack (Melee) Determined [B365] and Committed Attack (Melee) Determined [MA99-100].

For every +1 to your attack, you accept a -1 to your defenses. Additionally, you may not use the weapon or body party you used to attack with to defend at all, and you may not retreat.

It will surprise me not a bit to learn I'm not the first to suggest this.

You really need to address the movement. Committed Attack's two-step option and All Out Attack's forward half-move are very important aspects.
