You can cut either 4140 or stainless with HSS quite successfully. In
fact it was the common job shop method of machining nearly all metals
up to the 1970's when I left the business. And probably still is in
the smaller shops today.

Agreed, but unless I can postpone the job a day I have to use the
tooling already on the lathe and the metal in the scrap bin.

Of course. I thought you were saying that you were going to add
carbide tooling so that you could machine 4140 and/or stainless. I was
just saying that you could machine both materials with (what I
thought) would be the added cost of the carbide tooling.
