Highly improbable for the reason I outlined.
You can
only have 5 loan players in a match day squad. Given our reliance on loanee players in outfield positions, it would seem unlikely that the manager will assign two of these slots to goalkeepers when the chances of using the sub keeper are extremely remote. Doing this would limit the managers options for outfield loanee players - all of which feature regularly/start.
As we have 2 permanent keepers on the the books, I think the opportunities for Jokull to be involved on a match day (even as a sub) going forwards are now virtually zero if Carson has been brought here as the starter (which is surely the case, as he has stated his reason for leaving Dundee United is to get game time). If you were to select both Carson and Jokull, it would mean that you can't select one of the following:
Adam Phillips
Alfie McCalmont
Callum Jones
Jacob Bedeau
Any other players that we sign on loan
