Hey
Unfortunately this would require major engine changes, and while it is theoretically possible, I'm not convinced that it's worth it.
From my experience with rs training as well as with the script seems to tell me that you're better off using combat or super combat potions. While super combat potions are the best, they're a little pricey, however combat potions are incredibly cheap and do the job perfectly. What's more, the script will drink them as soon as the bonus drops so there's no need to worry about drops in exp rate. From an economic side, they're much better, and they pack a similar punch in less inventory space - but if you want the full bonus to strength then I recommend just sticking to super strengths.
Sorry about that! hopefully it's not tooo big of an issue though~
