We have Dual and Single Origin enhancements, as well as ATOs.
Why not Origin Specific Temp Powers?
Why not Archetype Specific Temp Powers?
They could even be pseudo-enhanced.
How would it work?
We have different types of salvage which can be classed as Magic (Arcane), Tech (Tech), Natural (Think, Iron, Gold, natural materials), Mutant (regenerating flesh, mutated genome etc.) and Science (Simple Chemical, Mathematic Formula, Scientific law etc.)
we could further classify them by effect:
Regen
Recovery
Smashing damage, lethal damage, Fire damage, Energy Damage, Psionic Damage etc.
Defense
Resist
Etc.
Then Let players "make recipes" by choosing components to fill the temp power's abilities
In Example:
PBAoE Damage:
Select an appropriate salvage to represent Damage type
Select an appropriate salvage to represent Form (what does it look like?)
Select an appropriate salvage to represent any Effect (Optional: Hold, Stun, Mez, Confuse, Immob, Sleep Etc.)
Select an appropriate salvage to represent Activation Type (Click, Auto, Toggle etc.)
Select an appropriate salvage to represent the Functionality (Think power sources and how those power sources are delivered)
Inf Crafting Cost (based on materials used and how likely it is to actually work)
Chance for failure.
Success = you are granted a Temp Power specific to your Origin and/or AT that has limited time or number of uses.
You can refill the timer and uses by feeding it inf and salvage at any crafting table. (Different from most normal Temp Powers which can only be crafted again once they run out)
And once at max uses Feeding it salvage and inf of one of the types used to craft it has a chance to enhance that aspect of the power. In example feeding it the salvage you denoted for damage type will have a chance to increase the damage output.
Best part?
The types of temp powers you can make will depend on your AT and Origin. so a tank making a blasting power might be possible but the accuracy and damage will be awful compared to if a ranged AT crafted a similar power.
Edit: Crafting a power different than your AT allows or substantially different from whats in your powersets (type and damage type etc.), has a higher chance of failure to craft initially, and a high chance of failure to refill the uses/timer.
Origin of the power could determine if it has any possible "Super Effectiveness" against specific enemy groups or if a buff it could grant different origins special protection from a specific enemy group while boosting Same Origin ATs with some additional team bonus.
Edit:Consider AT Specific Temp Powers and Origin Specific Temp Powers as:
ATTP: After living with your Powers for a while, and after having suitable practice with inventions (Min level 15-20) you are able to make some informed ideas about what sorts of things you could craft to make Powers suitable to have some ability to shore up your weaknesses and bolden your strengths.
OTP: After studying a lot about how you got your powers and why they work, and after having suitable practice with inventions, you are able to make some informed opinions about how to expand your arsenal via crafting.
