Bracket strategy for non-standard ensemble

What would be folks’ recommendations for a bracket strategy for a piece written for pairs of woodwinds (fl., ob., cl., bsn.), pairs of brasswinds (hn., tpt., tbn.) and timpani (single player)? “Small ensemble” (everything in one bracket), bracket per group with timpani hanging off the end? Something else?

Woodwinds together, Brass together, Timp by itself.
