The cleaner way in that case is probably to rename the type1 fonts to the
opentype name, and make the opentype version higher priority than the
opentype one in fontconfig

 <match target="scan">
    <test name="fullname">
      <string>type1 name</string>
    </test>
    <edit name="family">
      <string>opentype name</string>
    </edit>
    <edit name="fullname">
      <string>opentype fullname</string>
    </edit>
    <edit name="fontversion">
      <int>number lower than the opentype version</int>
    </edit>
  </match>

Though it sucks that you have to override the font version to change
same-name font priorities in fontconfig
