I wonder if the grammar point かえって (All the more, on the contrary)
https://bunpro.jp/grammar_points/464
…is the same as 変えて? I came across this sentence:
いつもと変えてたまに外で食事しよう。
(Like: contrary to our ordinary situation, let’s go occasionally out for dinner)
Is 変えて interchangeable with かえって or is it a completely different meaning then?
かえって is 却って. It’s possible that the sentence is using the wrong word or that it’s a typo, but I can’t say for sure.
I could see a sentence like いつもと違って[…]
But I don’t see how 変えて could fit at all given its meaning and the fact that it’s a transitive verb.
Aかえって(却って)B instead of what you would normally expect from A, B occurs.
So it is more about something like this:
健康のために運動したが、かえって怪我をした。
I trained for health, but, on the contrary, I injured myself.
The expectation was improvement of health, but instead the opposite (in a way) happened.
Also, 変える is る verb (ichidan verb), so て form is 変えて not かえって。
いつもと変えてたまに外で食事しよう。
Let’s occasionally change where we go to eat out.
By the way, this と is used to point a target of comparison.
Like in this grammar point:

Thanks! Yes, this と was the reason I thought it means “contrary”, but obviously I mixed up two different things 
I think literally the sentence
いつもと変えてたまに外で食事しよう
Means: “In comparison (contrary) to our usual behavioir, let’s change our habit and occasionally go out for dinner/meal” or in other words “why not go out for dinner today?”
So I thought 変えて and かえって are the same word (the kanji in Bunpro is missing, maybe you can add it?). Sometimes the casual form of the て form gets shortened to って, so I mistook both words.
