So that all parties are safe, how about the lender buy the ASIC shares 1K83 and then mine 3.3 BTC (3.0 BTC loan amount + 10%) for himself. Once he has earned the 3.3 BTC, he transfers the ASIC 1K83 shares over to you. Does that sound ok?
In that case, there would be virtually no difference in buying and keeping the shares themselves (and you might earn more so) as the risk involved here lies completely with the lender.
It would actually potentially make sense if the borrower were to some kind of "down payment"/"equity" so they would not be buying the shares with 100% borrowed money. Once the shares earn 3.3 BTC then they can be transferred to the borrower. This would prevent the lender from having to take on all the risk associated with buying the shares and would result in a completed deal.
Obviously it would mean that the lender would need to be extremely trustworthy (I think that Tomatocage meets that criteria, but most of the other lenders on here are probably not). Another potential twist would be that the lender sends an escrow funds for the loan, the borrower sends an escrow funds for his "down payment", the escrow buys the shares, and once they have earned 3.3 BTC the escrow transfers the 3.3 to the lender and the shares to the borrower.
