It makes perfect sense. You use your Roth as "pin money" and can do whatever you want with it since you don't need it to live. Your 401k account is a firewall - it's invested for aggressive growth, but not in a speculative manner. Your needs being met by other reliable income sources means you won't be hit with sequence of return risks if the market goes south, so you don't need a large cash or bond portfolio.
I'm in a similar situation, but as soon as I left my company (retired) I rolled the balance from a Fidelity managed 401k into a Fidelity IRA. Each year after that I rolled a variable amount from the taxable IRA to the Roth. My only mistake was not to be more aggressive in rolling to the Roth.
I mention company shenanigans as the company I worked for was bought out by a lowlife corporation just after I retired. The made a small name change, organized under a different LLC, and told Fidelity to transfer the 401s to a different organization (some miserable bank with limited investment opportunities). Those under 59.5 years old weren't allowed to roll their funds out as Fidelity was lied to and were told the company was the same.
