Uses of 'after all', 'withal', 'anyway', 'anyhow' instead of 'however'?

Suppose, a sentence is: 'He isn't qualified on paper; however, the interviewer recommends to hire him based on his great potential.' Can I use 'after all', 'withal', 'anyway' and 'anyhow' instead of 'however' in this sentence?

“Anyway” will change the tone, but you can use it in the end. As in “recommended to hire anyway”.

“Anyhow” means the same as anyway, but is informal.

“After all” usually indicates there were serious doubts. It is usable here but seems out of place. If it went like “he has a felony conviction and smells bad”, then “after all” would be justified.

If you want a viable alternative to “however” you could use “still” or “nonetheless”, or begin the sentence with “and yet.”

I cannot comment on “withal”. It is probably so archaic that I’ve never heard it.

Also. “Recommended to hire him”, not “him to hire”. Or him to be hired.
