Topic: new weapons

Was browsing some other threads and saw one about weapons that do damage based on cap. What about weapons that also scale with your cap. Example: weapon does x damage and costs y cap per shot. The difference is it takes 1% of current cap to increase damage by z%. T3 and t4 mods would scale by also increasing % current cap consumption to 2.5% and 5% respectively or something like that, maybe even increase base damage and flat consumption.
