If Kamran can clear the fitness tests that are the benchmark of this team then I guess he can come in as a specialist bat but in all honesty, if we breakdown the runs scored by him against whichever bowlers and then compare them to what's coming in Australia I guess we'd be setting ourselves for another massive massive horrid tour down under.
Scoring in Pakistan domestic (As per your own words earlier) is relatively easy and to base such numbers when we're about to have such an important tour could back fire in the grand scheme of things. Plus where would you field Senior Akmal ?? I am pretty sure I wouldn't trust him with any position behind the stumps !!
Also I seriously can't believe that after the Shenanigans of Mr. Kami in the last 2010 Aussie tour he is somehow or another making the rounds for yet another comeback

- Either he has the best PR agency behind him or our fans / selectors and other personnel in charge are gullible simpletons with a memory range of a Gold Fish !!
Have we all literally forgotten Sydney 2010 ????
You conveniently missed 4 key notes of my post -
1. Horizontal bat shot
2. Specialist bat
3. Form of his life
4. Specially for AUS tour
I guess for first 2, further explanation won't be required; but for the 3rd one - it's not about weather it's easy or tough scoring in PAK domestics (that I'll explain later), it's about the amount of run he is scoring now compared to any phase of his career, which indicats he is tremendous batting form - worth taking a risk. Regarding batting position, it's probably easier to fit in KAkmal in the line up from opening to No. 6 than most. In ideal world, he can replace YK at 4 or even Sami as opener; but he is scoring his runs from middle order, hence No. 4 is better.
Fitness indeed an issue, but that's probably default condition under Arthur - obviously unfit player won't make the cut for whatever, hence I didn't mention that. But for the other "question mark" - I think PAK is the last team to raise those shenanigans & my memory is indeed decent enough to know & recall some "history" - it's not even an issue with PAK cricket team - bowler, batsman, coach, manager, assistant, mentor, legend, umpire ..... take a random pick from anywhere......
Regarding scoring in PAK wicket - you have missed again. Scoring is not easy on those dead slow & low wickets - rather it's opposite, playing proper cricket shot is difficult - it's easier to play a game between cricket & hockey with ball coming at ankle high & dying. Result, news makers in QA run making tables are typical Azhar Ali staff - ZERO back lift, no back foot shot, no horizontal bat shot & no hit through the line on the rise - take a random pick - Fawad, Usman Sallauddin, Asif Zakir, Azhar, Misbah, Isharullah, Manzoor, Saeed Anwar Jr., Hasan Raza, Akbar ur Rahman .... I don't look at the stats much because the tournament is not balanced - over 600 players play FC cricket in a random selection of Corporate & regional teams & half of the players are not there on merit or purpose, hence stats often doesn't give confidence - couple of months back a young man scored a triple, not sure what he had done after that.
On such wickets, a player like Kamran is batting at 80/80 sort of stats for almost a thousand runs, means he is in tremendous touch. Cricket is a game of instinct, touch & cordinatikn (a bit luck as well) - the way Kamran is batting, I do feel it's his fortunate time now - that 150+ couple of days back is one of the best ever PAK domestic innings & it's not a fluke 60-70.
May not be for long term, but for this AUS tour particularly (this is the No. 4), he is definitely a better prospect than Rizwan, YK, Sami, may be even Azhar. In AUS, batsmen with single gear often set traps for own team - unless Azhar starts scoring at a faster rate from over 25 to 80; he'll cost PAK big time for his statically excellent batting.
Sorry for the long response, but I am a bit weak in English - can't explain in short.
