Dual Currency display plugin

Hello.
I know there are many multicurrency / currency switcher plugins out there.

But i’m looking for a specific plugin that has these features:
– It shows the currency that the customer has selected.
– It gets the currency exchange rates from fixer.io or another that provides free data.
– IMPORTANT: It does not change the sites actual currency, but only shows the “foreign” amount.
– It should process the payment with the default site currency (EUR in this case)
– Print the receipt with the default currency among with the customer currency

because the payment gateway i am using only accepts EUR.

And it should run ok with WPML also.
Thanks
