Given we cannot add new wikis to the existing growthexperiments-revise-tone enabled for testwiki, the proposal would be to create a new experiment, eg: growthexperiments-revise-tone-phase2 while keeping the first one only for QA purposes in testwiki. In terms of GE code this should be a one liner:

// ExperimentXLabManager.php
public const REVISE_TONE_EXPERIMENT = 'growthexperiments-revise-tone';
public const REVISE_TONE_EXPERIMENT_PHASE_2 = 'growthexperiments-revise-tone-phase-2';
public const VALID_EXPERIMENTS = [
   self::REVISE_TONE_EXPERIMENT,
   self::REVISE_TONE_EXPERIMENT_PHASE_2
];
