I feel like Morde should be able to build Hextech Revolver and Protobelt without extra damage
is great on Morde because of the hybrid stats, heal and slow from the active. But building this opts him out of getting the dash from
or the AOE slow from
. They all share the same cooldown because having all 3 actives available would simply add too much burst to any champ kit.
What I want to suggest is to allow the actives from the hextech items to combine without adding more burst or combined damage.
For example,
Combine 
to create the same dash active from
along with a slow from
.
Combine
for a longer dash. AOE from
is removed and damage is added to next basic attack along with a slow
Combine
and the
active now goes through minions and has a longer slow duration.
Combine all
for a powerful active that has a longer dash, powerful AOE slow that goes through minions.
All of the modified actives will have damage no higher than
or
to prevent too much burst.
The whole idea is to combine the utility of the actives without adding more damage.
This would make the hextech items unique and finally allow Morde and other champs to build more than one hextech item.
