Well, that doesn't really follow, because if we're recasting the roles, we don't know what this version of Beverly would look like.
The person who recast Troi based their choice on her similarity to Marina Sirtis, so I thought we were going for people who'd be at least reminiscent of the original cast. Hence Jensen Ackles as Riker started out in season one as something of a 'pretty boy' before proving he was capable of being more serious and tough. Ackles I think can cover both angles.
How about Alicia Witt for Beverley? She's 35, only three years younger than Gates was at the start of the original TNG and I've seen her play a professional on Law and Order.
