My question is, will the head space be a problem for the first 9 months when the barrel isn't full?
I might be misinterpreting your plan or perhaps its semantics, but are you thinking of this as a solera project or a blending experiment?
For a solera barrel that size you'd probably want to brew enough to initially fill the barrel full, let that beer go through a primary ferment (for head-space concerns mentioned), fill the barrel, age it, then pull/refill a portion after some time, & keep repeating the pull/refill process to achieve composite blends of aged sour beer.
