I don't know offhand, but I know enough to pull the Form 8889 instructions: https://www.irs.gov/pub/irs-pdf/i8889.pdf
Look at lines 3 and 6, it appears the straightforward answer is "no": "When figuring the amount to enter online 3, apply the following rules.
1. Use the family coverage amount if you or your spouse had an HDHP with family coverage. Disregard any plan with self-only coverage..."
I don't see any pathway where you can split the higher family limit to your HSA beyond the individual limit without being a spouse with HDHP family coverage.
