Find-as-you-type but with Filters

Is there any way to replace the default Find-as-you-type method with the Filter Bar? But without disable the Go (/) bar functionality?

Turn on Preferences / File Displays / Find-As-You-Type / Require activation key for Find mode and turn off Preferences / File Displays / Filter Bar / Activation key.

Yeah, but by turn on Require activation key for Find mode, you also lose the Go (/) mode. Any way to preserve this?

No, although you can still use F4 or Shift+Return to start typing a path.
