HSA Contribution when Spouse & Kids have a HDHP via COBRA

Through the end of this month (tomorrow), I am enrolled in my former employer's group health plan which covers myself, my wife, and our two kids. We have the ability for all of us continue with COBRA, or we can just have my wife and kids go on COBRA and have myself be uncovered. My question is, if only my wife and kids are covered under the HDHP (via COBRA), can we still make an HSA contribution up to the family limit? I ask because I already maxed out my contribution for 2025 ($8,550) to our only HSA which is in my name.
