A cracked shank on a briar pipe is usually fixable by banding because the technique involves a slightly tapered (conical) band and shockingly high compressive force to install.
Meer is an entirely different animal. It would be instantly destroyed if handled in the same way as briar. Any band used on it is purely decorative, and the shank material must be cut to fit a pre-existing tubular (parallel sided) band at the time of manufacture. "Retro fitting" a band to a meer would require the band to be made afterward to fit a specific pipe, jeweler-style; and then it couldn't be compressively functional, just a slip-fit tube.
I think you're screwed, in other words.
SP.com owns Peterson now, and they are, in my experience, excellent when it comes to customer service and customer relations. Try calling them before doing anything else. I predict you will be pleasantly surprised.
