There is a recurring problem in each re worded logline you post. You essentially have 2 separate inciting incidents these are:
1 – being disinherited
2 – being drafted into the army

As a result you have 2 major plots crammed into the one logline. You describe both inciting incidents and then describe only one goal for the second inciting incident fighting well in a war.

This makes for the first inciting incident of being disinherited come across as unrelated in motivation to the goal you describe of succeeding in war.

The extended description of the father’s reason for disinheriting the MC doesn’t add a compelling motivation for the MC. Also the character description of the MC makes him a generally dis-likable person perhaps describe a glaring flaw he can overcome as appose to upbringing circumstances (well off) and unsavory tendencies (trouble making). Perhaps immature or deluded would work better instead.

The concept has a fundamental problem with cause and effect between the inciting incident and the goal. If the MC is swindled in a deal I would expect him to NEED to get his money back not fight for his life.

So perhaps best to either re define the inciting incident or the goal to better fit a motivating need to drive the MC’s actions in the story.

Hope this helps.
