Yes, maybe, but I feel it goes deeper than that. You don't tease this character/group without it really meaning something to them specifically. Maybe BB makes his own Rocks group with other silver medalists (maybe this is how Oda repurposes Douglas Bullet or Tesoro or Z if they were ever canonized like Shiki), but I feel it still doesn't really apply to hiding Rocks as a character himself.
It also doesn't really align with the Lurking Legend thing involving Whitebeard. Unless Blackbeard just falls under another alias as Rocks and is him, beyond his inherited will.
