I don't think that it's a good idea. Most consume items are just better versions of normal items. Example with Shields.
- Nutshell Cake :
Apply 9 Shield, -2 hp, Consume (total gain of 7) - Shell Shield : Apply 4 Shield.
-> If you do something like "Remove consume, -4 Effect", then you'd get 5 Shield -2 hp on Nutshell Cake. There's really no point in this. These cards would provide the same thing.
What makes Consume cards stand out is their one-time bursts.
