I'd suggest just using .relr.dyn -- your encoding is straightforward
enough that I'd just make that the standard representation for this
section type.

Reducing code size of Position Independent Executables (PIE) by shrinking the size of dynamic relocations section

We've taken the '.relr.dyn' section from Cary's prototype, and implemented a
custom encoding to compactly represent the list of offsets. We're calling the
new compressed section '.relrz.dyn' (for relocations-relative-compressed).
The encoding used is a simple combination of delta-encoding and a bitmap of
offsets. The section consists of 64-bit entries: higher 8-bits contain delta
since last offset, and lower 56-bits contain a bitmap for which words to apply
the relocation to....
