How do I get diffs from two branches as a single commit and make it a new branch?

I have two branches called develop and feature, they both have lots of commits. Is there a way that I can make a branch called diff that it’s based on develop and has a single commit that makes contents of develop looks exactly like feature?

Basically diff and feature has the same content but it has a single commit that turns develop looks like feature.

• Before

feature - B - D - F - G
             /
develop A - C - E

• After

feature - B - D - F - G
             /
develop A - C - E - - -
                        \
diff                     H

G and H has same content so I can get rid of feature completely

>Solution :

git checkout -b diff feature
git reset --soft develop
git commit

or

git checkout -b diff develop
git read-tree -um feature
git commit

will do it.

Are you aware that what you’re asking for will also revert the changes in E?
