One issue with converting an income stream (e.g., pension, SS) into an asset using PV is that one does not know when one will die. Plus, an asset is something you own. You do not own your pension or SS. I point this out because they could change. This would affect the PV and change your asset allocation (AA). This would be too much for me.
I prefer to keep an income stream an income stream, which reduces WR from portfolio. I think that is the simplest, and tools like firecalc can model this scenario.
I agree with your desire to keep a high equity allocation for a long retirement. When I retired, I planned for 50 years. I chose 75% equities primarily based on
The Safe Withdrawal Rate Series.
