Robin McBryde and Neil Jenkins have been added to the Wales coaching staff for June's two-Test tour to Argentina.
McBryde and Jenkins can make the Wales jobs their own
Former Wales hooker McBryde is expected to fill the role of forwards coach, while world record Test points scorer Jenkins will work primarily on kicking.
That could see new Wales coach Gareth Jenkins make their positions permanent in his backroom staff.
"I'm delighted for them, I hope the outcomes are positive and we can go forward with this," Jenkins said.
"Welsh rugby has to realise specialist coaches are a big part of the top-end of the game now.
"We've got those type of young men, who've done it all as players and then been brought into the coach development system."
Jenkins has so far made only one permanent appointment to his Wales staff, taking his Llanelli Scarlets right-hand man Nigel Davies as attack coach.
Should McBryde and Jenkins make the positions their own, Wales will need just a defence and a fitness coach.
One possible replacement for ex-Wales defence coach Clive Griffiths was Saracens' Mike Ford, but he has agreed to join the England set-up.
Last September McBryde and ex-Wales and Lions fly-half Jenkins were appointed as skills coaches to groom the internationals of the future at the four Wales regional academies.
McBryde stepped up as Wales forwards coach for the tail-end of this year's Six Nations, in the reshuffle that followed Mike Ruddock's departure as head coach.
Wales will play the first Test against the Pumas in Puerto Madryn, Patagonia, on 11 June, before the second Test six days later in Buenos Aires.
