Hi Michael Buck - Thanks for reaching out over Q&A Forum.
Beginning 1 August 2022, you'll no longer be able to create new classic storage account resources.
So unfortunately, there doesn't seem to be an option to create a classic out on temporary basis
In case the account has been deleted very recently, you can reach out to support team to check on the feasibility of any kind of recovery on best effort basis. If that's not possible, then you might have to spin a new account and populate the data ahead in that.
Hope that helps!
Please let me know if there are any further queries/concerns, will be glad to assist.
