With gun attachments being bigger in CoD and Halo, sets with attachments such as fire effect gummies, scopes, and silencers, even if it meant cutting a figure from the stock 8(?) figures per bag chance, It would be really nice. Pre-Halo 4 scopes for the DMR don't exist yet, and it would be nice to see an alternative route to getting more in.
Accessories like Jetpacks etc would also be a welcome surprise since there were only 5 sets for both reach era and halo 4 era molds, Id hate for them to gather dust.
On a side note, I actually broke a SMG putting a CoD long barrel silencer on it for the slender barrel before the attachment nozzle. with the smaller pieces like silencers and scopes in larger sets, Id like to suggest and request a backup/spare piece because of their small size alone and usual dark appearance for them to be lost?
