Indeed. I see no point in unconditional doubling. I'm pretty confident
that /12 blocks are large enough to serve a RIR long enough so that
ordering a new /12 is not hampering anything.

My suggestion would be to set aside a /8 per RIR (perhaps also a DNS
reverse delegation for that) and allocate /12s to the RIRs upon their
request. A RIR qualifies for a new /12 block as soon as nn% usage of
the current /12 block is reached. nn might be 50% or more. As Randy
suggests, the percentage should be low enough so that the RIRs can
get new space without delaying allocation to LIRs (as it happens
nowadays).
