I'm kind of the opposite (so, with Haywire), if only because I already went and got the Deluxes.
I'd be fine with the Legacy Deluxe class molds for the original 3 and the Deluxe Insecticons (now with 100% more Venin). Then do a box set of the older Legends/whatever molds in the Diaclone colors. Just for cost and space reasons (and there's some charm to those smaller molds that I feel is kind of missing from these somewhat bland boxy takes). Although, knowing my love for these nth-string redecos, I'd probably get them if they used the Legacy molds (as is more likely) anyway.
