I made a bowling card for Ijaz Ahmed snr, the player you wanted to use as an all rounder.
You may add him to your list of all rounders if you like, he did bowl quite a lot of LM in the 1992 World Cup.
Ijaz Ahmed LM/SLA
Also you may add Shoaib Mohammad to list of part time bowlers, he bowled a lot in ODIs in the mid 80's.

They are both carded to average about 64.0 at 4.0 runs per over.
This is about as bad as it gets in this game, but can still produce a lucky wicket.
If there are any other part timers you want to use, they may use the same stats.
You will find bowlers already carded like Saleem Malik and Javed Miandad are rated better than
this.
Also, for example, a specialist bowler such as England's I.D.K.Salisbury LBG is better than part time in this game due to good A team performances and First Class stats, he is still a bowler and might average more like 45, but I can only guess for already carded players, I have no way of knowing exactly.
I can tell who have good strike rates and who are expensive, but little else.
You will find legends such as Imran Khan will match their career Test stats, and good First Class players who played very few Tests might average about 75% of their FC average, or better if they had a good ODI record.
