Instead I'd focus on being a 'special forces team' for people who have a good idea and some product &/or traction but need more people with your skill sets and access to capital.
You would then be essentially super hands-on investors, who could add significant value (although that really depends on you - you could also be super disruptive).
Over time you'd pick up a portfolio of companies that you've worked in and on, then exited and allow the initial team and new members you brought in to flourish.
While you rinse and repeat and slowly build network effects and improved learnings along the way.
