Absolutely opposite.
I haven't seen the kid, so can't tell about his bowling, but what you are suggesting is the Afridi way, where as youngsters should target Imran way.
In cricket, in any format (Ok, may not be in T20), the best match winners are bowling all-rounders - bowlers that make the team on bowling merit & can contribute with bat. The best ever I saw was Imran & in that regard, for Test matches at least, I would take Wasim, Hadlee, Warne or Marshall ahead of Sobers or Kallis - that's a separate debate, I won't explain here.
Now, this kid has the option to make PAK as a genuine leggi after Yasir, and he can add valuable runs from No. 8/9. Imran did that - starting from No. 10, ended up career at 3, but more than that, from a dibley-dobly, Imarn became the most lethal bowler, over a 3 years period, even compared to George Lohman or Syd Barnes (Check his stats from 1980 to 1983, before his stress fracture & then couple of years in 1986 & 1987, when he was 35+).
The difficult part is, it would ask him to double his work load - he has to be ready to bowl 3 hours in nets, then 2 hours batting & then other work outs. Imran used to bowl over 1000 overs in a County season & then bat at 4 - he must have put equal amount or more of work-load in nets as well. Afridi opted out the easy way - ended up as a nothing player. But, he had the talent to finish career with ~150 Tests, 7500+ runs at 35 & 450 wickets at 29; and equally impressive ODI career. In fact, he had a genuine chance of becoming the 1st & probably only player ever with 15K+ international runs & 1000+ International wickets; as being spinner, he had 2 decades of career; someone like Watson, Pollock or Crains simply couldn't last that long.
I again say, I haven't seen the boy - he might not be 17, but shouldn't be 23 either & leggis mature with age. He has lots, lots of time at hand. His idol should be Warne, Benaud or Qadir (Qadir was extremely under rated batsman) - someone who bowls 60+ overs in a Test & can contribute 35+runs/Test - that's a batting average of say 23. If he starts for Afridi way, he'll need Afridi like backing from all corners, to represent PAK more than 4/5 years. The reason is simple - he is not the best with bat, if he stops bowling (or can't make any impact), why should selectors pick him for 30s & 40s ahead of specialist bats, who also can share few overs. The best example of what'll happen is Mansoor Amzad - I saw him from Club house truing squire with a nice drift at U19 level, then he decided to compete with Afridi, ended up playing 1 or 2 matches for PAK.
Aamir, this kid, Ashghar, Aamad - all these players should target to make the team on bowling merit, then add value with their batting - that'll keep their nose ahead of Zia, Sadaf, Hamza or newbies. Anwar Alis are no body in Cricket, unless it's a 20 overs cartoon.
