Destroying 1* / 2* heroes
Destroying 100%
Sort of
If you spend food
Feed 1* 1.1 Hero A any 2* 1.1 Hero B
Feed Hero A to another 1* 1.1 hero C
Hero C is now Hero A
Repeat until all 2* 1.1 gone
Repeat using remaining 1* 1.1 heroes until all gone
Example
Level Petri, er, Derric 1* 1.1 with Layla 2* 1.1
Level Aife 1* 1.1 with this copy of Derric
Edit, When destroying 100% Hero XP, it costs 1 k food per 1* / 2* hero.
Other methods listed below will preserve 10% ( Destroy 90% ), or 5% ( Destroy 95% ), of Hero XP, but cost more food

Got curious, ran it a few time
No video uploads, see above screenshots
Edit, Faster is
Level a 1* 1.1 hero with 10x 1* / 2* heroes
Repeat until only 1 x 1* 1.1, and A x 1*
1.10 heroes are left
Level the last 1* 1.1 hero with the 1*
1.10 heroes
Reason
This works because 1* 1.1 heroes have the lowest food cost to level
Destroying 90%
Feed 1* 1.1 Hero Z with 1* heroes until maximum
You now have a Pseudo 1* Trainer hero
Create Pseudo 1* Trainers until 1* 1.1 are gone
Example
Level Derric 1* 1.1 with 1* 1.1 until maximum level
Repeat with other 1* heroes until 1* 1.1 are gone
Feed 2* 1.1 Hero Y with 2* heroes until maximum
You now have a Pseudo 2* Trainer hero
Create Pseudo 2* Trainers until 2* 1.1 are gone
Example
Level Layla 2* 1.1 with 2* 1.1 until maximum level
Repeat with other 2* heroes until 2* 1.1 are gone
Destroying 95%
Feed 1* 1.1 Hero Alpha with 1*, and 2*, heroes until maximum
You now have a Pseudo 1* Trainer hero
Create Pseudo 1* Trainers until 1* 1.1, and 2* 1.1, are gone
Example
Level Derric 1* 1.1 with 1* 1.1, and 2* 1.1, until maximum level
Repeat with other 1* heroes until 1* 1.1, and 2* 1.1, are gone

Vote to change remove the problem in the future
([Suggestion,QoL] Change 1* 1.1 / 2* 1.1 heroes into 1* 1.1 / 2* 1.1 Trainer heroes, zero roster space for trainer heroes and EHT on level up or update Camps, and Level up, for all/new players [Catch up mechanic])
