I'm not sure if this would change the tooltips correctly as you are expecting but the following adjustment code can be copied/pasted into a personal .user file or if the community wants to borrow it into their adjustment files. It has two dropdowns - the first looks for a weapon that must be in inventory, the second asks for the overriding attribute.

  <thing id="pXXWepAttr" name="Override Ability Modifier for Weapon (Attack and Damage)" description="Override the ability modifier for a weapon attack." compset="InPlay">
    <tag group="OthAdjCat" tag="Equipment"/>
    <tag group="Helper" tag="NoIncr"/>
    <tag group="Helper" tag="AdjNoPlus"/>
    <tag group="Adjustment" tag="YourWep"/>
    <tag group="Adjust2nd" tag="Attribute"/>
    <eval phase="PostAttr" priority="10000"><![CDATA[      ~ If we're not enabled, get out now
      doneif (field[pIsOn].value = 0)
      ~if nothing's been chosen, get out now
      doneif (field[pChosen].ischosen = 0)
      doneif (field[pChosen2].ischosen = 0)
      ~ Pull selected ability tags
      perform field[pChosen2].chosen.pulltags[DamageOver.?]

    </thing>
