Reports are claiming that the long rumored replacement for DNI Dan Coats will be GOP Rep. John Ratcliffe, who has played a prominent role in the House investigation of the Russia Hoax. As a former US Attorney (ED Texas) Ratcliffe was especially active and effective in questioning witnesses. The Hill has one of the more extensive accounts: Trump expected to nominate Texas GOP lawmaker to replace Dan Coats: report.
On its face, I tend to favor this idea at this point in time. As a former USA, Ratcliffe should work well with Barr, Durham, and Horowitz and less likely to be controlled by Deep State operatives. Or so I'd like to think.
The other names that have been mentioned all tend to fall, IMO, within a more standard Deep State mold.
