Don't do RTO. Instead, layoff (with cause) all L10-L12 staff excluding technical IC's (including Andy, S-Team). L8's already have enough knowledge to effectively run the company. Problem solved.
RTO effectively dismisses the best staff, keeps the fat (L10-L12 staff excluding technical IC's), hires low performing replacement resources at cheaper cost of labor. However, the savings from removing the L10-L12 fat will by far exceed the 'savings' from the RTO approach. AND... it would strengthen the teams and culture!!
