How can I reduce this child pom further before generating 800 similar poms or is it impossible?

Question

I will have like 800 of these child pom files/modules, so I want to get this one right and reduced as much as humanly possible before I start the other 799 child poms.

Things I would specifically like to address, things that will not change across all 800 child poms, but that I do not know how accomplish:

• project tag attributes are long and repeated from the parent attributes.
• model version is repeated
• parent tag is always the same, but intelliJ gives code highlighting issues when missing
• plugin tag: the only thing that differs is the configuration, must you really include the first 3 lines in every single child pom?
• plugin/configuration/group tag: intelliJ gives code highlighting error when not there, but works with or without it. I would like to remove it because the parent defines it.

The Child Pom:

You can move the <build> section to the parent POM. The rest must stay.

The natural question that arises is of course: Are you really (really) sure you need 800 of these modules? Maybe your original problem has a simpler solution. It would be interesting to know the background.
