I totally get - and support - the R2 philosophy of not making the kit something it isn't. If you are sitting on a stack of RRs aned GTX's (everyone has a few in the pile) then it's pretty much a no-brainer for a Coronet.
Economics of the hobby would suggest that a full on new tool kit is a big investment, and needs to be approached like the Moby B's and Novas,or the promising looking Revell Boss 351.
A revival that ain't fish nor fowl would make it more expensive, but not necessarily better.
Possibility is out there to handle the HT the way AMT/MPC did with the '70 Coronet R/T in the 90s - toss the more detailed chassis/engine in the box and send it.
Also raises the possibility of a Pro Street (even thought I'm a bit weary of the idea) version, the chassis was high water for the genre, and would be a Tab-A, Slot-B solutions.,
