I have posted a piece here which is also on the TT topic, but is more general and I think a new thread would be better. Your voice is heard. See below.
Didn't one of the manufacturers come up with similar-ish solution a few years ago - basically it was a pair of DIN rail mounted terminals sat next to the incomer (perhaps even with twin screw terminals for the tails entering from the bottom) and then some links from the top of the terminals to the incomer's top terminals. Admittedly that retained the screw terminals rather than crimp to the meter tails - but that does allow some flexibility in re-using exiting tails and/or avoiding (possibly dubious) on-site crimping.
